I doubt 14.1 has ever even crossed their backers minds.
If Schmidt or Harriman managed to get "their" backers to put a $50,000 race to 1000 point challenge match on a standard Diamond table offer together to present to SVB and his backer I would not be surprised to see it get accepted, with SVB then practicing 14.1 for a few weeks, and Schmidt or Harriman not liking it one bit come game time.
The reason this match will not go off is not because of SVB's backers, it is because there is no chance that the backers for the other guys are going to offer a match worth enough money to SVB and his backers to get him to bother with a game he rarely plays. They know if they do it will be a case of "be careful what you wish for, because you just might get it."
