I can't speak to how easy / tricky it is to work with the mirror assembly, but I can say that there could be a hidden gotcha.
Some years back I knocked mirrors with a parked car and ended up replacing the glass (and the adapter on the glass back). Somehow, as a side result of that, the assembly motor now does the weird "don't lower when backing, only when coming out of reverse into drive" trick. Diagnostics at the dealer showed that the signals reach the mirror assembly, but that something after that goes wrong.
Then again, that's with Lucas, and I forget the exact year of the Bosch change-over now...
Since the dealer price for the switch-out is $500+ (at least in IA), I'd say it's definitively worth giving it a go yourself.
