#4 Special stipulation for Reigns vs. Mahal MITB match?

Roman Reigns and Jinder Mahal are supposed to square off at Money in the Bank. And yet, when Mahal challenged Reigns to a match on RAW, he accepted. That makes me wonder, why would you have the same match...both on RAW and at the pay-per-view? Could the pay-per-view match have a very special stipulation attached?
I can totally imagine the match between the two men to be a 'Chairs' match. While that match may be a more apt contest for the upcoming Extreme Rules pay-per-view, it would provide an added dimension to Reigns vs. Mahal. There's no other earthly explanation for the two men squaring off twice, less than 7 days removed.
As for the match on RAW, there's a big possibility that there will be interference from Mahal's trusted Singh brother leading to a bust. Expect there to be a no contest, this week.
