I feel the LMB/CC/BG combo will require the least intensive management, will provide the most return on fillets, will be the most self sustaining fishery since you DON'T want to use a feeding program. My recommendation is based on all those goals you stated...if you change one, fishery recommendation changes, too.
You may end up with a LMB heavy population, which will mean many stunted LMB and fewer, but trophy, BG. Or, you can end up with the inverse situation. You don't have to do anything to manage/change that situation if you can live with it. If you want a BALANCED fishery, it will require management of either population depending on which is out of balance. You can have a balanced fishery or imbalanced BG or LMB fishery - frankly I feel each scenario has it's merits. All depends on your goals. Culled LMB are fine for hot peanut oil and a skillet.
