The way they do things now is this: First are TV commercials, then movie trailers, then the movie. I think I remember an ad for Agents of SHIELD in one of the commercials shortly before the trailers started (and before the M&Ms told me to turn off my cellphone). I think that's the best you can hope for. The movie studios aren't going to appreciate their trailer time being taken up for a TV show and to have it during the movie seems tacky to me. Those credits at the end are the same credits that air on home DVD and deserve to be devoted to the people who made the movie. That being said, I wish it were the "after the events in Captain America The Winter Soldier, nothing will be the same" commercial that aired to make it clear how big the tie-in was.
