Use the mod VioLens. You can adjust the frequency or completely disable killmoves. It should be compatible.

Shadow God battlemage set added. It has the enchantments of the mage set with the warrior set's armor and weight. It's an additional option when you pick the set up, so this doesn't replace anything.

I was annoyed that there were no heavy armor mage sets so I made this quick mod and turned the Blood Mage set, sans the hood, into heavy armor. I've only changed the armor type and switched the hood and helmet's armor ratings (hood used to be better), since the armor isn't that far from the equivale...
