Uh-Oh....
As CJ stated HBG are not good for a balanced fishery. What size feed are you using right now? A 1" BG won't be able to eat anything very big, unless you're reducing the size of the pellets even further you may not be accomplishing much by trying to feed. Have you asked around to see what size CNBG and RES are available to you?

What size are the LMB you were thinking of adding? Nearly any Bass between 3-8" will adore a 1" BG.

I'm wondering about adding some catfish and 4-6" LMB now, then 3-5" CNBG and RES in a few months, but that's backwards from the usual recommendations.
What would happen if you added the bigger CNBG and RES now, and used the existing HBG as forage for them? Hopefully someone with more knowledge than myself will have a better plan...

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
