Which themes are best for Multi Site / Buddy Press instalations?

I am building a Multi Site Buddy press install to promote High School Athletes and help them get scholarships. Here is a link to the site http://PlayerProfilesToday.com

The question I have is about themes for the athletes inner site - Example here


We have Athletes in Football, Baseball, Track,Tennis and just about anything else in the future. I would like to set up themes that they could easily select for their page.

So a Football theme a baseball theme and so on.

I have a Genesis developer license and a Thesis developer license and I have a wpmudev account also.

What would you think would be the best way to go about this?
