I'm sure you'll get a lot of opinions on this, but if it were me, I'd stock a few smallies this fall, perhaps 10-15. If you had pretty good numbers of GSH and FHM, they should make it through the winter, and they'll be ready to go when the BG are spawning in the spring and early summer. Then add more SMB next summer/fall as early as you can get them. I would consider WE as well, especially if you have some pretty steep banks and deep water structure.
You'll likely find that certain of your smallies do quite well on BG and will adapt to BG as primary forage; you can cull those that do not seem to be thriving on this diet. With your kids aggressively targeting the BG that grow out of the preferred smallie range, you should be able to manage quite well.
