An ESPN journalist recently did a survey from across college football (coaches, players, ADs, etc), looking at what big changes they expect in the next few years. Wrote a long article on what he found. It's pretty good. I'll link it down below.
One part of the article was about what possible rule changes the 200 or so people poll favored and/or expected. The three most popular on-field rule changes mentioned were:
1. Giving replay officials more discretion on whether a player called for targeting should be ejected. (about two-thirds supported this change)
2. Allowing helmet speakers for QBs to ease communication with coaches. (about two-thirds here, too)
3.
Making a player whose injury stops the clock sit out for the rest off the series (almost half supported this)
So that's pretty strong support. It will only grow as games continue to be over-long. Hopefully in the next year or so, it will have enough momentum to become a reality.
