I have a MA/Bio Brute who has costumes I've tied to each of the Adaptations, that I then swap to using macros like so:
/macro cce 0 ccAnyCostumeChange$$powexecname "Specific Adaptation"
However, when I use the macros, more often than not, I change costumes, and activate the Adaptation like the macro is supposed to, but the animation of the Adaptation doesn't actually appear, except for a moment during the costume change emote itself. It's not consistent, but it's more common than the animations working as intended.
