I don't thnik skipping the breaks altogether would be any good. But I can imagine shortening them could actually be a good move for the BB game.
make breaks between Q1 and Q2 and betwen Q3 and Q4 2 minutes instead of 3. It's just enough for a leak, or even grab a soda if wanted, but it's not too long to wait out for the next Q to start.
At halftime 6 minutes or 9 minutes would be better then 12 as well.
For BBs profit, they can do commercials at half time as well.
BBs have been thinking about cheerleaders as well, but they couldn't figure out how to implement. they asked a specific fed to help out, but there where not enough members in the fed, and they never came up with anything decent either.
But if someone comes up with something worked out, and not too hard to implement, I think they'll have ears for it. So creative minds... go ahead!

An other tip is to use the chat feature. It's nice to talk to others watching games in your country. And during half time, you don't miss any action. Boost about the score, ask tactical questions to other managers, show off with your player's performance,... it's a great way to kill the time.
For those desperatly seeking for more entertainment still, there's youtube to watch, and yuo can watch almost anything there, during those 12 minutes.

They are not your friends; they dispise you. I am the only one you can count on. Trust me.
