OK, so here's the scoop:
Let's assume that you're going to have to be a human. This also helps out with the whole concept of being a shifty Dex-based fighter, as your racial bonus can be applied to Dex rather than Wis and Cha, as is the case with Aasimar racial bonuses. This is pretty easy to change, but hey, I like to min-max occasionally, especially when I'm statting up someone else :D
If you're really in love with the concept of an Aasimar, then you might want to take a page out of 3.5's Unearthed Arcana, and claim a celestial bloodline. If your DM pushes it, this can be pretty easily nerfed into just a fluffy background element without any mechanical influence.
I'm assuming that we go for an 8th-level fighter, as that seems like a good medium-term goal that you can build up to. Just take any of the feats listed in the block below as you progress and what not. Stylistically, it seems like you want to play a very technical, swashbuckling-type fighter, which would mean that your charisma would be pretty high for RP purposes. You'd also need a reasonable intelligence for any technical options you might want to take. So, your wisdom would probably have to be your dump stat.
Above and beyond what you have on your wishlist, you still have a number of slots left open depending on where you want to go. You could get better at attack, defense, mobility, or RP. Just switch out Shield Focus, Greater Shield Focus, or Iron Will for any of the following:
Attack: Greater Weapon Focus (rapier), Weapon Specialization (rapier)
Defense: Toughness, Combat Expertise, Wind Stance, Lightning Stance
Mobility: Lunge, Fleet, Nimble Moves, Acrobatic Steps
RP: any skill feats, Leadership
To start out, you'd look something like this:
Stats: Str 16, Dex 17, Con 13, Int 14, Wis 7, Cha 13
Equipment: rapier, longbow, chain shirt, buckler, potion of cure light wounds, 40 gp
Feats: Dodge, Weapon Finesse, Iron Will
So, onto the stat block! Your character should look somewhat like this when you've leveled up quite a bit.
