Welcome to PBF.
If you want to add some diversity to the gene pool, buy some large adult BG or catch them from another source. Large enough so your largest bass can't eat them. If you and your budies could catch 30 or so 7-8" Quality BG from another BOW that would give the BG genetics and breeding population a boost. I upgraded non-existant BG population in my old pond by doing just that by catching adults from my main pond.
IIRC, PB warned us that stocking large adult LMB from another BOW into our waters may not work well because the fish might not adapt to their new environment. Based on your comment, that advice apparently does not apply to BG.
I think you're right. But why are large BG able to readily adapt when large LMB often cannot?
