No.
@Nick Mang and
@FrayedAdversity can do this stuff too.
The plan would be to use things like CFalc's get up attack for Sheik's down smash. The biggest issue is that grounded animations suck because they change the characters height when copied onto another character. Aerial animations, however, don't have this issue.
Edit: quote from frayed
"that's not new or hard to do. mario luigi and fox are interchangeable"
"
@Danny_SsB and
@felipe_9595 were doing this 5 years ago"
Edit 2:
