Don't know either Akuma or Pai Mei, but Yoda I do know quite well lol.  I say you're doing a good job Rev, and you can do what you like with Shang-qing except send us to war since it'll be Chaos and Cosmos that start the mess as they always do.  Most likely it'll be Chaos that does it since he is the war like demon and all lol.  Beyond that, feel free to interact with who you like on any side as much as you like except as I said, starting the war yourself.
