Loads more great suggestions. Thanks to everyone.
That custom Beastman is great maxxev. Its a little more work intensive that I am aiming for for my MotU project, but it looks fantastic.

Top left on that would be easy to convert into a Tri-Clops I reckon, plus top middle is another Trap Jaw option.

It should be easy enough to make a Beast-Man and Moss-an out of that set.
