I would recommend just jumping up and down and announcing that you're doing it, as that would be the fastest and most direct route to seeing how viable it is.

However, since we're here anyway, I'll offer my opinion of it:

It seems like it would be rather slow, although pretty interesting. The logistics of organizing it could be fairly difficult, seeing as the players will spend a lot of time inactive. Also, if you're streaming it, you'll need to be casting several games at once, which would require multiple streams.

Good luck in your venture, and, if you do decide to try this, I'll help out wherever and however possible, if you would like.
