We are having a hard time finding a suitable microcontroller for our new

In addition to the other comments I'd recommend not running your clock
close to the highest rated speed, and I'd also have you check on the
ratings of supporting components such as capactitors and XTAL
oscilators.

A/D conversion is likely to be spotty near the temperature extremes
also (check the spec sheets carefully - I know that Silabs is one
company that specs A/D for the whole temp range but I don't know about
the others). I'd design the whole system with at least a 20% margin to
hedge my bet.
