This is kind of an off-the-wall idea, but... what about creating artificial meat substitutes for these prized exotic animals?

Couldn't Beyond Meat create a pretty close facsimile to pangolin or bat or snake or whatever? Obviously this wouldn't eliminate 100% of demand. Particularly among those eating the animals for their magical properties, instead of their taste. But even if artificial versions of exotic meats could cut consumption by 20-30%, the corresponding risk of zoonotic virus transmission should fall linearly along with that.
