I think it would be neat if somehow (if he has them) the EX moves/Supers Ken uses would use Bison more in unison, like maybe doing from a tatsu into a knee press, or hadou/shoryu into psycho crusher. I do think his sprite is a bit too distracting when using the moves himself, I think making him look more like a puppeteer may work best, this is really crudely thrown together, but it's just some grab edits with his intro pose. I think something like this may work better if maybe he did something like this whenever Ken attacks, and maybe use the psycho energy effects on his hand (or just a palette effect idk) He could maintain his hand stretched out maybe as long as Ken is actively in combat. The idea is super neat and I think it's interesting for sure, best of luck with this, look forward to seeing more updates!
Maybe instead of such a wide hurtbox, hurting Bison, could use his vanish sprites to dissipate him for a while if he takes too many hits, losing his assistance for a little while, kind of like the stands in the Capcom Jojo game, just an idea.
My rough example of what a few sprite edits can do for making him look like he's conducting Ken.
