As much as i would like that, i just dont fully agree with having copy ablility moves on his A attacks, save for the few attacks from Fighter, his dash attack from Yo Yo, and his Suplex throws. For some reason i just feel that they'd be better on his special moves.

I was thinking that Kirby could have something similar to 0.7 Sora's Magic Swap.
Something like using Down-B to change powers and special attacks.

Yeah that'd be cool, but i doubt the developers would consider replacing Stone lol. Although, why not, other characters have had moves replaced, so i dont see why not, besides, its not like Stone is that important in the series anyway, most secrets that can be accessed with Stone, can also be accessed with Hammer.

Don't forget, if Stone was removed and Power Swap (Name I thought up) was implemented, Stone could be chosen as one of the powers, but the devs would have to make special moves for Stone in order for it to work.

If you mean like choosing Stone, and then all other special moves become Stone based? I could see that working, cuz for the grounded up special could be the stone uppercut from Return to Dreamland, and his Side special could be him turning into a boulder and sliding forward lol. Unless you meant replacing one special move (which would be a lot easier lol)

1st Bold: Yup, it could work that way, but Power Swap would replace Stone, and also give Kirby Stone-based special moves when chosen as his power.
2nd Bold: IMO the power chosen should have special moves that are based on Kirby's power, but if only replacing one move was easier for the devs, it would still work either way.

The only thing is that Stone has no applicable abilities for a recovery move, so either they'd have to improvise, or just remove Stone from the list altogether and just give other abilities that can apply to his specials like Sword

Well, I thought of a recovery move, but it sounds kinda stupid...
How about Kirby taking stones off of his body and using them to throw forward as a horizontal recovery, similar to Yoshi's Up-B in 0.8?

I don't really think Kirby should be changed, the only characters that (In my opinion) need move changes are...

Mario: Down B

Fox: Final Smash

Falco: Final Smash

Wolf: Final Smash

(I think one Starfox character should keep the landmaster final smash.)

Donkey Kong: Final Smash

Diddy Kong: Down B

(If they remove tripping.)

Metaknight: B

I think everything else is fine and evenly balanced.

Well, side B could be an option, and I don't see why not. But if they implement that sort of thing, then it would be either redundant or unfair to be able to inhale as well (or illogical, but then again, what's logical in Kirby?)

Well, that means that if Power Swap did come in SSB4, Inhale would have to be a part of when Kirby has no powers active.
Also, about the recovery dilemma, the devs could increase Kirby's jump recovery to make it go higher or something when he jumps.

Hmm, I don't know, because I doubt there would be a recovery dilemma with every one of Kirby's abilities. I'm pretty sure that the only way this would work now, after some contemplation, is to set the power swap to Down-B, with Normal, Fire, and a few other common abilities, which would be used with Neutral-B. Any stolen powers from inhaling in Normal mode would be lost if you tried to switch with Down-B. Perhaps Side-B could also be implemented, but Up-B should not get involved in the power swap.
