I think that this is a good idea for rising stars. Also, this means that some elements of the x division are coming into the heavyweight division which will make the world title picture more intresting.
As far as the x division championship is concerned, I think they can bring back 6 sides for destination x again (annualy) and then they can do the terror dome/steel asylum; the winner gets the belt.
I have a list fo things they can do for every PPV and the destination x ppv and x division are involved.:
Genesis:average PPV, make something huge happen so we know whats coming for the whole year
Against All Odds: Similar to option C; a new wretler can join the heavyweight division, not only x division though
Victory road: hype lockdwon
Lockdown: it's ok how it is with every match a steel cage but for the x division; Xscape match
Sacrifice:Bring back the Ultimate Sacrifice matches back
Slammiversery: KOTM, do something with the TNA originals like a Fortune reunion
DESTINATION X: Option C, the terror dome(x division), a elevation x match(TV title), ultimate X(tag), and Xscape match because it will be a six sided cage match for the remainders of those not up to anything
Hard(core) Justice: Every or at least one match Hardcore.
No surrender: Finals of BFG series
BFG: the winner of BFG series in main event, one monsters ball match, that happens annualy apart from last year. Battel Royal for those not upto anything,promote it more!
Turning point:Aftermath of BFG; good impacts
Final Resolution: Something great to end off the year.
The matches that are for those who are not doing anything, the winner can earn something.
