If you want trophy/large BG that can be done in the small pond with LMB. A feeder will help. What is hard to do is have a balanced small pond with BG and LMB. This is because of the reproductive nature of the 2 species. They both tend to overpopulate which causes managing for balance to be similar to balancing on a knife edge - attempting to maintain an unstable state between 2 stable end results (BG crowded or LMB crowded are stable conditions). The LMB crowded state (easy to maintain) will provide a population of large BG due to most of the small ones being eaten leaving more food for the survivors.
I would use the large pond for SMB and other fish (no LMB and no BG). You have lots of options. YP , RES , FH , GShiners , WE , trout and more.
