I believe the '05-'06 glass might be just a bit thicker, for sound deadening purposes - if memory serves.
My only concern about the AA-sized batteries is whether they will deliver enough amperage - but yes, an arrangement like that is what I had in mind. You could test it on your car (assuming you have nearly infinite patience for removing and replacing panels). If the "23A" is an amperage rating and not a model designation (hard to believe in a battery that small), it would work. Looking at the listing for it, I think it is an alternate model designation for that battery, which is "A23," - not an amperage rating. 23 amps is HUGE for a small battery. Most of the fuses in our cars don't go that high (though some are 30 amp, and the pre-fuses are far more). Still, that amount of amperage is coming from a pretty large main battery.
You MAY find that the window lift motor has a socket by which it can be manually cranked with a drill, with no power applied to the motor. Pinkster's diagrams seem to indicate so, but I am not at all certain. See the M10/6x1 and M10/5x1 designations in his first pdf above, and the photo below. That round device with the spoke grid (and at the arrow below) may be the cranking point.
Also, we were cross-posting. Your quote missed the following, which I was adding at the time - it may be helpful when putting things back together (don't ask me how i learned about it - yeah, the hard way) - Post 10 at http://www.benzworld.org/forums/w220...-exterior.html
has a pdf file attachment with more on the door panel removal; it was written to address replacement of the interior door handle LED, but the latter portions of it discuss the latch cable in greater detail than the video, as well as the clips that could pop off when you lift the panel from the window frame. I just wanted to be sure you saw it.
