How hard is it to transfer hardware into a new door shell?

[lbrowne]

My passenger door is pretty rotted at the bottom. To get a new skin welded on costs significantly more than an entire door shell.

I have an all-power door, how hard would it be to transfer the guts to another new shell? I figured if I got a used door I would have to sand and paint it, why not just start with new metal...

I'm sure many have done it. I've changed handles, moldings and key cylinders on later model vehicles - but the whole power window setup and installing the glass is uncharted territory for me...
