Hey Dinger,
yes back when I was first making the first leaps into the modding API as a proof of concept, all I had was player-models with tint colours added to tell the difference between each droid type. There is significant code changes to adjust to the new "Johnny 5" style sprites, so it will be difficult to revert those to the tinted droids from the v1.3/4 era of my mod.
I may introduce the humanoid troops back into the game with a different mod/s, related to hiring mercenary soldiers as bodyguards or hunters. Along with my "Civilisation"/Sim City mod aspects, with "civilians" and having to feed them. I wanted to make a mod to add colonists that need upkeep as a sort of end-game goal.
