I think the jarred specimen idea is awesome! And if you want to do taxidermy as well what's stopping you from doing both?

Before my ex room mate "lost" (sold/got rid of) my storage boxes, I had a collection of skulls, articulated roadkill skeletons, and dried things in jars (no wet specimens). It may not appeal to a lot of people, but there is definitely a market there for you to utilize. Just recently I was thinking about starting a wet specimen collection As stated before, morph or not it'll lose it's color, but I don't see why you shouldn't do it
