My thinking...and now I'm second guessing....was that as opposed to removing the lamp with it's mounting bracket....remove the lamp and leave the bracket in the car. Once it's unbolted you can get one hand in from the front...one from the back and remove/replace the bracket from the lamp.
When I did a headlight replacement in my former '96 GTS, I seem to remember slipping the lamp (less bracket) through either the foglight front hole or the plug in order to get more access to the headlight hardware without pulling the fascia. It's well over 10 years ago since doing this, and I can't remember the details as well as I'd like. Perhaps I masking taped and gently flexed the front foglight hole to slip the lamp out without it's bracket? (And yes, I was able to change the headlamp without pulling the fascia)
Some of the plastic retainers for the fascia are tough to put back in with the headlamps, etc in place. I pulled the fascia on the RT and despite having a lift...it wasn't exactly a two minute job.
For that reason, I'd try to do the lamp without pulling the fascia first. Unbolt the lamp/bracket from fascia. 3 bolts. Then, seperate the lamp from the bracket. If the lamp by itself can't be brought past the front or rear holes...then pull the fascia. You're not going to have much more work to try it first.
