Maybe you could make yours Blitz . Like, "Blitz " with an intentional space at the end? I don't know if that would be allowed, but it might work. Just a thought.
How about Вlitz? I use the cyrillic "В" rather than the latin "B", only problem is that you won't be easy to ping.
You...probably have to tell people regarding the pinging otherwise they're gonna end up pinging the other guy.
