I understand where @LyfeWithDragons is coming from, especially about looking professional but personally I don't think your URL matters that much. 99% of the time people are going to search for your username or watch your videos from their subscribtion feed, just think about it, how many times do you go to a channel by typing in its URL? I'm saying this from personal experience because I was in the same situation like @TheUnicornScribe, I started posting on a channel that I set up years before and didn't think I would stick with it so my URL is different from my channel name but I think I'm doing just fine.
It's up to you whether you want to make a new channel or not though, this is just my opinion.
