Oum is the graphics guy who was first made relatively famous a few years back when he made the Haloid short movie, a kinda crossover/fight it out between Samus and Master Chief, and the Dead Fantasy series, which never caught my attention, I'll admit. more recently, he was the guy behind the RWBY series, which has now become the first animation to be dubbed into japanese.
That said, I still think it's not a bad idea to include tribute names like those, though maybe they should be more nicknames than official names. While I don't think there are any real problems with making the tributes to people we respected, there is a certain element of unoriginality to it.
