You don't have to rework all of the specials, but I would suggest making down-b a counter move that triggers a small Chaos Blast instead of trying to figure out Chaos Boost. It's gotta be easier to do than Chaos Boost, and would be more practical and easier to balance. Even if you could figure out a way to implement Chaos Boost properly, balancing it would be very difficult, if not impossible.
And for the record, I'm 23 and never really played Shadow the Hedgehog. The idea of guns in Sonic game was just laughable to me. I still own my original Sega genesis, and still have the cartridges of the good games in the Sonic the Hedgehog series. I was just throwing the idea of the guns in there for a laugh. Maybe you should add it as taunt, like how Ganon flashes his sword.
