Yeah, it'd be cool, but what's stopping people from buying a ghost texture for 5k making it black and saying it's void? If it cost 30USD then sure, but the way you proposed it would ruin the entire ghost section of the market and probably damage the economy.
More like a DQ Texture where you have to pay money to get it and there's a limited amount.
Generally not supported
Hello
my idea and get ghost texture could cost 1k-4K
I think it would be cool :3
Perhaps a change to your idea. An item that allows your ghost to represent your tori better. that way you couldn't change the colors on it, it'd just be.. you. But see through and less vibrant.
