No, and maybe, but probably not.
For a lure to be neutrally buoyant, the overall density needs to be 1.0 g/cc, the same as fresh water. Alumisol has a density a little less then that, but lead has a density much higher (11.3 g/cc). This means that for every cc of lead, you would need to replace 11.3 cc of plastic with microballons.
So, if you have a really small lead jig head, and a really large bait, then yes. But, for more practical applications, it is not reasonable.
Adding microballons to the plastic can float hooks, etc., so the concept works. It is a matter of scale.
