Hate to bring up the cost-thing, but I can't fathon buying a cage that costs 10 TIMES more than it would to build myself. Plus, do plastic cages hold heat very well? Probably not as well as a plywood cage. Thus you might get spikes in temperatures, which is not desireable. Just two bad things I could think of. Other than that there is definitely a market for cages Chris. I think it would work for sure!
