You can probably just "bump" the team up by posting a comment on it or editing it. That will get your team up to the top of the recent activity section. I don't think you can hide and repost though. That would be unfair, and if we did allow it, the RMT would basically be like a war or people reporting their teams and trying to get attention.
Honestly you're lucky to get a response in the RMT section. When you post an RMT, just know that the competitive part of this site isn't big enough for every team to be rated, so yours might not get a response.
