Project M gameplay in Brawl help?

[Syeo]

Hi there,
I'm getting more interested in Project M but for me, it's still too early to use it completely. I decided just to use the FitMotionEtc.pacs + FitCharacter.pacs. It works perfectly (still causes some legs, for example Pikachu using his fast dash while pressing A), but the characters just fall down when they are kicked out of a stage. They don't even resist, they just keep falling and die, that's kinda annoying. Is this problem also in Project M or did I forget to add something?

I tied to just use the fighter files myself and it caused problems especially for samus it froze the game , you have to use all the files in order for everything to work

Since the CPUs caused some trouble and it didn't work properly, I decided to go back to VBrawl again.

Well, even though it isn't completely topic related, but is it possible to use Project M with cBliss + Stage Expansion so I can keep all of my characters (except the ones with FitMotion) and stages? Or are there some troubles that might occur when doing so?

Edit: Oh, I should mention that I'm still new to Project M, but I know that it doesn't use cBliss but something else so characters with the same color are in the same group. So I wonder if they are compatible.
