Biggest bass I have every caught was on a live bluegill. 23 inches. I was about 13 years old. Never forgot it.
I would just free line the bluegill or....use a weighted hook.
I've read where you can use a weighted hook with a two baitfish one hooked through the tail and the other through the upper body on the same weighted hook. This make them really thrash against one another. Creates alot of vibration in the water. I might try it out tomorrow
