It is highly unlikely. The only things you can do are:
1. Knock down the SMB to such low numbers that they cannot eat all of the FHM you introduce. This means to zero.
2. Introduce another fish species that is too large for them to eat, Yellow Perch for example. Their offspring could stimulate the food chain a bit andmin general are a fun fish.
3. Same goes with pumpkin seed sunfish, or even both.
4. Have tons of cover such as heavy plant growth that the FHM can hide in, and a lot of items like pallets and other structure they can breed on. However I think that would result in skinny bass that could no longer efficiently catch food.
Feeding FHM is a sure way to an empty bank account. I started with FHM in my pond a few years ago, and thanks to perch, walleye, and black crappie introduced later, they are almost gone already. They were established, but not any more.
