Obviously no, but I think I know what you were getting at. Here's a question:

REG line, and a trip of yours that's a week away goes 23K for equipment sub, and the revised rotation actually pays more. And then you PB it. Should you be paid for the original, the revised, or the greater of the 2?

I'm not 100% sure as I have never had 23k, but I'm pretty sure you would get the greater of the 2 at the time the PB was executed. Seems to me that DDH should be similar.

Nobody is, or at least nobody should be, arguing that reroute pay pays for something you don't fly. It's VERY clear that you only get paid reroute pay for reroutes that you actually fly.
