This is a little off topic, but it seems counter productive, or bad marketing to name an incompatible, and different mutation altogether, a different line of an existing morph. If a buyer is looking for a recessive animal that will clean up a project, they have to go with a hypo or ghost. But since most hypos are compatible, and blue and greens are only compatible with themselves, most people will go with compatible lines to be safe. But if the incompatible lines were given different names altogether, like a spirit ball or something, that would offer an entire new morph option, and more people would probably decide to go with the rarer spirit ball than to decide on an incompatible line of the hypo phenotype. Or maybe not. I'm just thinking out loud.
I agree, if I discovered a new morph that looked similar to something else, but was not compatible, I would give it a whole new name. Not only does this avoid confusion, but it protects the value of the new morph(as you stated).
