Any luck with changing animations?

[UnLucky]

I was just trying to see just what all I could do with this game with the ol' copy paste method, but it doesn't look like I can switch animations around.

As a test, I replaced the Demoness's move, start, and stop animation lines in the .atom file with those of the Dryad's, and even tried physically replacing the proper .bsa files. The idea was to see if I could get her to soar over obstacles properly, or at least hilariously. But nothing happens! When I try to move the unit, it plays no animation at all. Doesn't even slide or warp to the destination cell, just freezes in a neutral stance. Ugh.

I can give them 3 move and the Soars ability, but that just means they'll walk through rocks and things. I just want to give a little love to a neglected part of her body.

Is there something I'm missing, or is it impossible to do short of designing new animations from scratch using the specific model?
