Nah. I don't think it's a problem. Up to you if you want to delete it or keep the Razor videos around in this thread but I don't think anybody will be that confused.
Separating them is fine. "The Styx" is a good title for Styxhexahammer. Not sure what to do for Razor.
Side note about Styx, I love his Fallout 4 Minuteman flag he has in his videos occasionally. And the SPQR one.
