A thing that I'm doing, with all the 6mm Aliens available now. From CinC, Onslaught, Microworld, etc., many can be Tau Allies/Auxiliaries. Also in the original SM1 rules, and we still use many of those, Chaos could have Ork Freebooterz/Mercs. I use some of the other Aliens available today to fill that slot as well.
For what rules to use ... I'm a K.I.S.S. Fan ... Many aliens I just use SM stats ... But nothing says you can't write up some rules for you local gaming crew for other aliens. But again K.I.S.S. Or better yet Do What Works For U.
You can think out of the "GW box". Commissars and the =][= will not be showing up to where you are gaming to see how and what that you are using to play Epic ...
And I'm going waaay off the GW tomes. And making an Alien Galaxtic Legion with many of the different 6mm Aliens being made today. It's a BIG Galaxy ... there are more aliens out there beyond what is in GW 40K "fluff". Which changes frequently ...
