New Brevoort Formspring

In an older interview about the launch of ANXM, BMB said this was an idea that could only happen once. He tried to think of what other characters could do it, but he felt is was something that "feels like the X-Men". He's done great work, in my opinion, and I'm sure that if anything similar happened some would complain about the lack of originality, but I really would like to see something like happen (or have someone go back to the past), even as a story arc and not an ongoing. Any chances?
