ive actually been a huge proponent of a TV-14 show that is separate from the flagship monday night raw show. kevin nash brought up that idea on a shoot interview once.
On some site (here? Reddit?), someone had suggested that the WWE revive both ECW and WCW, and let the former be the raunchy/AE late night show and the latter be the kid/family friendly saturday or sunday show. I always thought that'd be a good idea.
