'Soon'?
I am in favor of differentiating their designs, but not so much their characters. They should look similar enough to obviously be the same species, but there is room for variation.
Morgoth will have two balrogs in his throne room at all times. Certainly, he can talk to them. But they are just yes-men, goons. Unless one of them is unexpectedly funny, we aren't going to get to know them.
I am thinking of the Mystics in The Dark Crystal. Each of them has a unique look, and a different role/job in their village. But the audience views them collectively, with the exception of their leader. Their role in the story is very much interchangeable. The Skekses, on the other hand, the audience has more time to get to know, with their internal politics and ambitions. I don't think we need that with balrogs.
So, I am fine assigning them names, so we can keep track of who does what, but I think the question of differentiation should be left up to the artists. I don't think it's a matter of establishing separate characters on screen.
