I don't know if anyone's using Bb in corps yet; we'll have to wait & see how it turns out within five years.
But, Joe's right -- it can be done, and you need to pull out the 1st and 2nd slides to match the new pitch. As a matter of fact, at least one corps (Crossmen) has done this, using Yamaha 201-style tubas with the 3rd valve permanently welded down. It had to be welded so that they could honestly say there's no way it could be used; that was way before the 3-valve rule, too.
