Should R Rated Movies and Pg 13 movies be connected?

All the talk that one of the movies DC is planning is Suicide Squad I have to ask. There is no way Characters like the Suicide Squad, Deadpool, Punisher or a Jason Todd could fit into a Pg 13 movie and still stay true and be a good movie. So Lets Say Marvel makes another Blade or Punisher Movie (If they got the rights back) Should they connect it to their already established movies? How about the Suicide Squad or Jason Todd? If either got movies should it be apart of the Universe Man Of Steel started?

As far as Marvel, I don't think they should connect it with their already established movies. In order to keep the integrity of the characters they would have to put it in a separate Marvel Knights Universe. And for DC, Vertigo Universe.

I would love to see Christopher Nolan do a Rated-R Punisher.

I don't think R rated films would ever happen inside the main universes (Avengers, JLA) from the two main companies. But I love the idea of R rated stand alone films. I wouldn't want to see (JK I would absolutely see it) a PG-13 Suicide Squad, Punisher, or Deadpool film. It could definitely work though, think about how Watchmen was able to capture its tone. It couldn't have done that with a PG-13 rating.
