If it were me, and it's not, I would stock about 1,000 three to four inch bluegills and get them started. I would simultaneously stock about 100 4 to 6 inch bass. Within a couple of years you should have a fairly balanced fishery.
This is essentially the same formula I used to finally put a dent in my GSF population. They're still there, but no where near the typical "stunted" GSF population most people face in old farm ponds.
