Lomion

I have been writing a story of a time long before the time of Sauron's domination.

The story sets two Maiar falling in love despite the different background they came from.

However, I named them Nimeria and Lomion. I have just found out, after much researching of the Silmarillion, that Lomion turned out to be a name of Maeglin. If I continued with my Maiar named Lomion, would it be alright? Would there be licenses for the name? And how could I distinguish the two apart for my readers' better understanding?
