I only made fix for the original mod, so as far as im concerned there is only space suit variant.

do they different clothes or just the space suit?

here it is.

mmm hell yeah if it isn't so much trouble

This happens because I disabled them for randomly spawned empires, so that no one would encounter species with spaceshiba/bear portrait while playing with these portraits. Unfortunately, this restriction applies to customly created empires too.
I can make a separate mod that doesn't have this restriction, If you wish.

even with empire spawning forced, the empires with spaceshiba and spacebear do not spawn!
