With only 30 seconds to evaluate this, I think you have to fold because:

1. You figure that you are only slightly ahead of the reraiser's range given how tight the table has been playing.
2. The big stack's presence sweetens the pot enough to justify gambling with the reraiser but doesn't sweeten it enough to go broke with your own big stack in 10th when he (the other big stack) does have a real hand.

Given more time to run the numbers, it might be a push, but I think it's going to be slightly +$EV at best.
