It sounds logical, but before dumping the LMB into another BOW, I'd ask around if anyone else in the area wanted them for their ponds, or wanted them to eat. Ask at some of the food banks and churches. Some will take fish/game.
While HSB aren't a large predator of BG like LMB are, that'd be another option. They normally won't spawn in a pond, so you wouldn't have to worry about them overeating the forage base.
But, and that's a big BUT, do some fish sampling and check the relative weights before adding anything to the pond.
I'd especially keep an eye on the Crappie size and numbers. They can throw a pond out of balance too.
