I am just a noob, so take my advice for what it is worth. But with bluegill I wouldn't imagine you would need to stock anymore to reach your goal of more bluegill to bass. With more food your bluegill are going to breed more and grow faster, thereby escaping predation quicker too I would imagine.
All in all, your bluegill will bump up their own numbers for cheaper then you could buy more.
Also, if your looking for a fish to give the bluegill a break, many people are using tilapia. I am not sure if they are legal in your neck of the woods, but they breed like crazy, eat algea and weeds, are good eating. and die off when the water gets too cold (diffrent strains at diffrent temps - ask rainman)
So tilapia could be a self sustaining food boost for the bass, instead of an expensive one time snack like fhm would be.
Just things to think over.
