Just a thought, but if you are going to have to stud it out at all (a simple drawing would be helpful if you could whip one up) I'd try and run some small ducting channels behind the paneling to circulate more air. Use computer fans linked together on one or two circuits (heck you could just rig an old computer power supply to a bunch of them) and have that plugged into an electronic timer.

I'd also get a nice wireless or remote electric hygrometer & temperature device so you can have a read-out LCD panel on the outside by the door for easy monitoring. I'd also make sure that all the electrical switches and whatnot for fans, lighting, etc. were on the outside of the room again for easy access.
