Is G&W easier to mod than other characters?

[SrslyOsm]

I notice there are a lot fewer of him, which is guess is either because
1. He is more difficult to mod over.
or,
2. His 2D-ness isn't much use to most people.

Even though his moveset doesn't match very well, I wanted to make Rayman Origins styled 2D mods of Rayman, Globox and possibly Betilla. Possible, or very difficult?

[ForOhFor Error]

Probably pretty difficult.
