The trans patterns are too different. Not to mention you have to take the front plate off the AX15 which is the guide for the throw out bearing and put it on the 10/5 which won’t match. In short, nothing will move over. If you had another AX15 say internal slave set up, then hell yeah everything will swap over. Most guys will say if the 10/5 shifts fine internally and isn’t a struggle, put a new slave cylinder and go and source your parts to swap to the 15 until then if you want to play the patient game.
