That sounds... kinda awesome.
Anyways, what you do is what Batman is doing. They release a kids cartoon (Brave and the Bold - my 3 and 5 year old nephews love it). They release a more mature Batman cartoon (The Batman, Direct to DVD movies, Timm-verse Batman, etc etc), and then they also release the adult Batman (Nolan movies) stuff. It's all about effective targeted marketing.
Also I don't really see why they have to reach "Deadwood" levels of maturity. Hell, just hitting a Farscape/Angel/DS9/LOST level of maturity would be more than enough.
