In all seriousness, what I'm looking for is additional mass in order to shift the center of mass forward. By filling the nose cone with epoxy and lead shot, have I not created a solid mass capable of inficting significant damage to any object that it might impact should something go wrong? Additionally, I wouldn't be able to remove this mass should I use a lighter motor.
Why is lead, zinc or other dense material the only option? It seems to me that sand, dry clay or any other natural material either in the nose cone or in a bag would be a viable option. And cheap too!

Because it is dense and can be put at the very tip of the nose cone, allowing you to use less weight overall. If you use material that is less dense, it can't be placed as far forward (fills much more volume, including back toward the CP), requiring you to use much more weight than necessary. Due to it's increased weight and inertia, it could be more dangerous. A nosecone full of sand will rip you a new one just as fast as a nosecone with a little bird shot and epoxy.
