I've been thinking about this lately. I was thinking about how Zayn and Neville could get the opportunity to put on a match like they had at (R)Evolution on the main roster. The conclusion I came to was that they probably couldn't, unless they were in the main event, which probably won't happen. They don't give their midcard time to breathe because their events are booked like variety shows instead of wrestling shows. There's all this external stuff they consider like merch sales and Total Divas and yadda yadda whatever.
A lot of people say the IC title doesn't matter because it gets passed around so much. But that seems like only half the problem. If they gave every IC title match at least 20 minutes on each PPV, it would do wonders for the belt. If a feud ending match got more than 8 minutes on RAW with a commercial break in the middle, then maybe people would care more about the guys coming out of the feud. I supposed this would involve fewer matches on the card overall and less variety bullshit which is obviously impossible, but it would do wonders for the under card.
