With the top line bass predators in the pond, and lack of weed cover, it will be difficult to establish the smaller prey species.
You could either yank out the LMB and as many SMB as soon as possible, then restock the SMB once you know the minnow population was established. If not, you probably can count on the majority of the stocked minnows being fast fish food.
Or stock HSB instead of the SMB. Then if the lepomis and YP seem to be getting out of hand, then stock some SMB, or more HSB. In that small of a pond you might have a hard time keeping the predator/prey balance without a lot of intensive catch and keep. Then ony the actively biting fish are kept, leaving the more closed mouthed ones in the pond........
