Is this legal?
Pirate Weapons (Ex)
A corsair is well versed in the types of weapons favored by pirates. When selecting a group of weapons for his Weapon Training ability, he can select Pirate Weapons as a group.
The Pirate Weapons group consists of the crossbow, cutlass, dagger, hook hand, rapier, and short sword.
You can stab your enemies with your sword or another slashing weapon.
Prerequisite(s): Dex 13, Weapon Finesse, Weapon Focus with chosen weapon.
Benefit: Choose one kind of one-handed slashing weapon (such as the longsword). When wielding your chosen weapon one-handed, you can treat it as a one-handed piercing melee weapon for all feats and class abilities that require such a weapon (such as a swashbuckler's or a duelist's precise strike) and you can add your Dexterity modifier instead of your Strength modifier to that weapon's damage. The weapon must be one appropriate for your size
If this is legal, can it be used with crossbows (Light or hand), would this allow you to use feats that require you to attack with a melee weapon with a crossbow, but not feats that require you to make a melee attack
How about when used in conjunction with the blade adept arcanist? What about with the double crossbow and kensai Magus?
Bladebound kensai? How would it work with these two feats?
I'm essentially looking for anything that would work with these.
Your post is very confusing. You seem to have listed several different abilities and feats all together without labeling them.
If I understand you, this is your approach:
1. Get Slashing grace with a Cutlass.
2. Use Martial Versatility to use Slashing Grace with all the weapons in the Pirate Weapon weapon group, which includes Crossbows.
Is that what you are saying?

Yes, and furthering itself to "Can the affects of certain feats and class abilities requiring a melee weapon be applied to crossbows by this"
You can not use Slashing Grace with crossbows. One handed is a category of weapons, one that crossbows are not in. Crossbows are ranged weapons, light crossbows can be used in one hand but are not "one handed weapons". Not all weapons that are used in one hand are "one handed weapons".
Sorry but the feat specifically applies the effects of one feat with a specific weapon to all weapons in said fighter weapon group (pirate weapon group includes crossbows AND cutlass), so technically that point is specifically overridden.
...Specific
...
I do not see that anywhere in your post.
I didn't think anyone out there didn't know this evil feat by heart
Martial Versatility (Combat, Human)
You broaden your study of weapons to encompass multiple similar weapons.
Prerequisites: Fighter level 4th, human.
Benefit: Choose one combat feat you know that applies to a specific weapon (e.g., Weapon Focus). You can use that feat with any weapon within the same weapon group.
Special: You may take this feat more than once. Each time it applies to a different feat.
Are crossbows a melee weapon? (No)
So there is the simplest answer, not melee weapon (technically one hand slashing melee), so no it wont work. Only thing it will help is the cutlass.
I think you can but it's still useless.Benefit: Choose one kind of one-handed slashing weapon (such as the longsword). When wielding your chosen weapon one-handed, you can treat it as a one-handed piercing melee weapon for all feats and class abilities that require such a weapon (such as a swashbuckler's or a duelist's precise strike) and you can add your Dexterity modifier instead of your Strength modifier to that weapon's damage. The weapon must be one appropriate for your sizeThis means that you can add dex to damage... if you could already add strength to damage with a crossbow. Which doesn't happen.

If a feat only requires that you be using a one-handed piercing weapon (or some superset thereof) then it works. If it requires you to make a melee attack, then it does not.
I figured on the first point, but the second I wasn't quite sure...
so in theory an arcanist could have a black crossbow for example?
A slightly less cheesy(though admittedly still cheesy) possibility:
A Fighter picks up Slashing Grace(Battleaxe) and Martial Versatility(Slashing Grace) to spread that out to the Axes group. Can he now add his Dex to damage when throwing a Throwing Axe?

What about strength and a half in relation to thrown two handed axes and the two handed thrower feat?
But now you're just making me ask way cheesier questions, like throwing oversized splash weapons

Why go to that trouble. Just use a Sibat and save the Martial Versatility feat. Though you could use it for the Amentum and get a 50' range with a thrown weapon.
So from the looks of it, yes, you can totally have a black crossbow.At 1st level, a blade adept develops a bond with a blade and infuses it with arcane power. This ability works like a wizard's arcane bond ability save that the blade adept must bond to a one-handed piercing or slashing melee weapon. Additionally, the blade adept gains proficiency with the weapon if it is a simple or martial weapon.I'm not sure how much of the powers are actually useful for a ranged weapon but it looks like it's possible. There are also some feats it screws up (Hamatula Strike) because it implies (but does not state) that you have to use it with a melee attack. Actually, I just realized that you can use that one with a crossbow without any of these hoops, and it still makes no sense.
Maybe use a rope?
This is making me want to make a really cheesey build
