I suspect the money collection would be the problem. I don't know that just talking about the idea is any kind of policy issue, but if you actively started soliciting money--even for something like this that I suspect most people would think was a good idea, at least in a generic sense--I think it might be frowned upon. We have no way to know if you're on the up-and-up or just a common thief, after all.
I think if you wanted to do something like this, you'd have to work through a well-established .org. It might be something to propose to DITD, if you're really serious. Then you could probably spread the word about it here.
