I'm not sure why you want to combine them in the first place, but I wouldn't risk it. I would just grow a colony larger by keeping some holdbacks if you want a larger colony. They are temperamental enough without newcomers. That's just me though. I had the best success with 1.3-5 groups. When one was getting up there in age, I'd let a young one stay in there and feed off the adult that was ending it's reproductive usefulness. 1.1 or 1.2's seemed to have a lot of cannibalism for me.
