Gaming a BBJ

If a BBJ was big enough, and the poker site was ignorant to what was going on (seems unlikely - but maybe they know and don't care as it doesn't hurt their bottom line), could a BBJ be gamed?

6 players open the max number of tables on a site together and limp every hand that contains a pair or any two cards that can make a straight flush. Maybe they bet the river as normal in order to maintain the appearance of playing 'normally'. They could even improve on this strategy by sharing hole cards and only betting flops or turns when they know no-one can make a BBJ. They could also find more folds doing so when one player has straight-flush possible cards that are blocked by anothers', or when they both have the same pair in their hands.

I guess the two key questions would be what strategy to use that both maximises chances of hitting the BBJ, at the lowest cost, that also escapes the attention of the poker site, and at what size BBJ it becomes profitable.

Seems like something you could set a solver on, presumably with the data piped ino some Python.
