[New/ Changed Melee]

Is there a way to perhaps swap Shepard's melee animation? Just basic stuff like infiltrator melee to engineer for say

 

The other question is is it possible to replace shepard's combat animation set? Like change it, including melee to a multiplayer characters set

 

So you could move dodge and melee like an n7 shadow for example

 

Has anyone attempted this? If so what were the hurdles you faced
