AoS characters in Marvel movies?

Just wondering if we will ever see any cross over in the Movies from AoS characters.

Obviously Coulsen was in several of the Phase 1 movies, tieing them together until his "death" in Avengers.

Several of the movie characters have made guest appearances on AoS, including Fury, Maria Hill, Sif, among others.

Just wondering if we'll see Skye in a Marvel film, or Coulsen again, or any of the others, even in cameo form. Such as Fitz and Simmons working with Banner or Stark on something.

Would it be too much of a stretch? or do you think it would be nice to tie it all together.

Just curious on thoughts.

I kind of hope that Skye will at least be seen in the Inhumans movie. But who knows how that will go, and if that will be focused entirely on the "royal family".
