It's hard to predict just what will happen.

I think at first, and for a couple years, you will have great LMB growth, but with no BG control, the BG will stunt eventually from a lack of food to feed them,..and then your big bass will be eating all they can (and expending far too much energy) just to survive, instead of thriving and growing.

Trophy bass are difficult in any situation, but to have the best outcome, I believe like ewest said, you need a near balanced situation of reproduction and forage variety for ALL species.
