Trying to make Godzilla Kaiju earrings

Hi, jewelry makers! I'm trying to make my partner earrings with one of the Kaiju monsters (e.g. Godzilla, Mothra, Ghidorah, etc.) but I can't find any charms that are small enough. Even more difficult is the fact that he wants the earrings to be posts, not hooks.

Any ideas on how I could make such a pair?
