How do I mix motion/move set mods?

[Awesometeen956000]

This is my first time here so excuse me if this is in the wrong area, the reason this question is here is because both the mods i wish to combine are compatable with Project M. they are the "Ultra Sword V2(Brawl/Project M 3.6)" and the "Sm4sh Side Special for PM Kirby" I've attempted to tinker mixing these mods with brawlbox, but every attempt lead to failure, all of them failed to change the animations of the hammer side B. The only noticable changes were the fact the final smash did some weird stuff that all end in T-Posing that can't be stopped. If anyone can help me out it would be a big help.
