No, it is not.
If anything, there should be slightly less aggression between two males of similar species than between two males of the same species. Yes, there will still be aggression, but theres no reason that it would be MORE than two same species same sex animals.
(unless, of course, rather than 4 leucs in a tank, you're talking 4 leucs and 2 tincs, in which case, increased aggression is more caused by increased population density than any mixing concerns)
