Hey Guys, Happy New Year!
There are several ways to skin this cat. Here are some that come to mind.
1. You can roto-mold a skin of super plastic and fill it with a less dense material as has been suggested.
2.You can imbed a premade shape(s) of more buoyant material into your main body.
3.You can imbed steel rods, vinyl tubing or plastic straws through your mold which can be easily removed after it cures. When removed it leaves an air chamber that can be plugged on each end and left full of air, or fill with 320 foam. Obviously rattle, balls, etc can be added but careful not to glue them together. When i was a kid i used liquid mercury in the chamber! Please do not do that. did not know any better then.
4.You can pour your lure from straight resin, then add a buoyant material to the top, just like you would add lead strips to the bottom of a floating lure to make it sink. After you get an idea of how much and where, you patch it in using dremel, drill, saw or what ever it takes! All the same rules apply, including compensating for the material you have removed.
Think of it as reverse keel, reverse balance. Anti gravity...
best,
