Let . By previous problem we have that for and thus on that interval
That said, using Lebniz's differentiation under the integral technique (checking that it's applicable) we find that
Thus, our integral is .
It's amazing how I don't realize that many of the problems I post are interconnected until you point it out to me.

Yeah, but I'm often lazy and just look for the quickest most mechanical solution, you take time and come up with neat non-obvious solutions. So, in the end, which is better?
Can we justify changing the order of integration, or is my solution invalid?
