It seems to me that the best way to show CBS that a production company won't make a profit from their IP is to set up a non-profit organization, like a 501(c)3. It would have to comply with established regulations, and all moneys generated would be directed toward expenses. Any revenue not spent would be put back into the treasury for future expenditures.
I don't know the mechanics of it, but I've seen it work in other applications. An attorney would be able to work out the kinks.
