It all depends on the size of your leos; if you want to keep leos together in the same enclosure, they must be around the same size. Bullying can occur if one leo is larger than the other (over food, space, hides, etc.), so I personally wouldn't do it.
I have a giant albino that is kept with many of my non giant females during breeding season. they do well. He is a big baby though, so I cant say every gecko will be behave the same.
