I don't see why it could work more than once a year provided that the Gimmick PPVs were being replaced and that the PPV had actual choices that weren't rigged either. Just take all the gimmicks from the gimmick PPVs:hardcore, ladder, table, chair, TLC, cage, hiac and make a few of those stipulations in the matches upon which people can vote on. That way the gimmicks are still there but the ppv isn't themed to one gimmick. Each match can have a diff set of 2-3 stips to choose from. For example the above card could look like this:
CM Punk verses Ryback - tables match or hardcore match
John Cena verses Dolph Ziggler-ladder match or cage match
Sheamus verses Big Show - tlc match or hiac
then for the extra drawing power mid card matches like tag team division could have something like
hell no vs ptp vs sin cara/mysterio- elimination table, hell in a cell, ladder
this would give the opportunity for the first ever tag hell in a cell.
then lower matches could be something like
orton vs del rio with special referee - rosa mendez, ricardo, mick foley, brad maddox
cesaro vs barrett vs kofi vs truth- elimination fatal fourway, two title on a pole match( inwhich the belts are on diff side of the ring and either can be grabbed, leaving the option for the a current champ to capture both, and adding a new strategic dynamic as someone like cesaro wouldnt be so much concerned with winning as guarding his corner), arm wrestling tournament(lol)
Then the divas can have:
heel dica vs face diva - regular match or bra and panties(lol obviously the vote would be like 90% to 10%)
Anyways the point is instead of having extreme rules, hiac, tlc etc we could just have 2-3 of these to still cover those bases and really put their social media to use. It wouldn't reall take the value away from it because rather than the predicatable scheduled gimmick, we can still have our gimmicks but as surprises. They would just need to use legit choices and legit voting and not some bs like hardcore match or pie eating contest.
