Would it sell? Yeah, betcha a fair sum that unless the price was completely outlandish, you'd sell five, maybe ten of them.
Now, how many do you need to sell to keep your big fortune from becoming a little one? It's not just "Can it sell?", it's "Can it sell enough units, fast enough, and at enough of a price, to bring in more money than the company spent producing it, plus a salary, taxes, insurance, etc., for everyone involved?"
As a one-off, I smile every time I see it. Guy sure has a great sense of humor. :gig:
I like it. If done in a module fashion, a kit may be viable. Think of the number of college sports teams and the crazy things people do to show support. Make it easy enough to do many of the mascots and you may have a winning formula.
