It probably wouldn't cut down on sweat buildup in the suit during the dive, but might let it out after the dive, so could work from that standpoint..
The other problem with Goretex is that it relies on micropores to let the vapour out but not let liquid in.
Those pores can and do get clogged - diving in the sea almost gaurantees the material will loose its breathability very fast.
Fun fact of the day - Goretex is expanded PTFE. PTFE = teflon, the same stuff the plumbers tape and the non-stick coating on cooking utensils are made of.
Consider how easily scratched non-stick pans are, and how soft and tearable PTFE tape is, and ask yourself if you REALLY want a drysuit made out of the same stuff
I'll stick with a Weezle and waterproof drysuit for now, I think..
