Need more Aliens

I really wish we got more aliens in sets. I'm making my own Star wars oc collection mostly just using sets and that means my minifigures so far are 99% Human with the exception of an Akbar clone and a D&D Tiefling I converted into a jedi. I really want more unique/alien looking minifgures to make it more realistic. Have there been any recent sets with good alien figures? I thought about getting the Plo Koon micro-fighter but it's hard to have a Plo Koon mini-fig and not see it as anything...
