Help with custom follower and sexlab compatibility

[ari777]

Im currently in the process of making a custom follower mod and a freind of mine is modifying a base male head,hands exported from skyrim in 3ds max.The gist is there changing the facial shapes adding animal ears ,new hair and changing the male hands to have long nails for this follower"youkai character" . The body that will be used is from sos schlongs. My question is should i be concerned that the follower will have no expression or lipsync at all sense they will have custom dialouge , all i want is just standard emotes from the game nothing fancy.Also any other technical issues i should be concerned with like rerigging and how to import the new objs, textures to a nif . And lastly will they work properly with sexlab
