Bloodrager / Medium Mulitclassing?

[Boozehammer]

Hello, Pathfinder community! I am currently attempting to build a Ganzi character concept and am looking for suggestions for multiclassing. Attempting to stick to the chaotic narrative of the race, I am hoping to multiclass utilizing the CHA racial boost. My first thoughts were to use a Bloodrager/Medium build to take advantage of the Champion Spirit to boost the Bloodrager's melee prowess. The advice I seek is then twofold:

1.) Is there a way to make this build viable and competitive?
2.) If so, what class features and feats would you suggest I take to make this build work?

While a dip in bloodrager could boost a medium's melee prowess I'm not sure that works the other way round. A medium gets good stuff at 4 levels in, or 6 levels in, or even further down the track. Not so much as a dip.

A one-level dip in bloodrager with the extra rage feat is an easy way to boost the effectiveness of a medium in melee combat. You may well want the raging vitality feat too & the ganzi con bonus would make it fairly easy to qualify for. Assuming that you also want power attack that takes care of your early feats. (Improved) legendary influence to give you more flexibility wouldn't be bad after those.

I would be on the opposite end of the spectrum.

A single level dip in Medium is pretty amazing for any martial character. Or rather, any character that isn't focused on spells/spell damage.

Champion is great as you noted, but also throw in Spirit Focus(Champion) and the Spirit-Bonded enchantment (medium armor only, +6,000 gp). Now you are at +4 to hit(and fortitude saves) and +6 (non-spell) damage rolls. You pretty much have all of Champion's shtick with just a single level. Sure, you don't get an extra attack at 6, or pseudo-pounce at 11, but you get all of the bloodrager things instead.

As a dip, you get some added class skills, 2 cantrips, +2 will save, and a couple uses of spirit surge (trading the weapon proficiencies for extra uses) as well.

Of course, I think its even better for classes that use multiple weapons(natural or otherwise), or unusual weapons (alchemist, gunslinger).

If you really wanted, and you were playing in a home game, you can take that Legendary Influence to pick up some crafting feats. Take Spirit Focus with Champion of course. Then take something like Craft Wand with Archmage, Craft Arms and Armor with Trickster, Brew Potion with Hierophant, Craft Wondrous with Marshall, etc. Since you will have access to whatever 1st level Wizard or Cleric spell you want, you can make wands/potions of whatever seems fun at a much lower price. Arms and Armor/Wondrous so you can upgrade most of your "Big 6" at cost as well. Trickster will increase your skill check a slight bit as well for when you need to ignore requirements.

+3/+5 that is, not +4/+6. Unless you take 4 levels of Medium.

So, below you'll find the build I've been working on. I've actually decided to take a lvl in fighter as well to gain an extra feat, so it's made it a little complicated. Would y'all mind looking at it and given critiques/corrections?
