So firstly, is this a stupid idea?

Adirondack chairs have been around for a while, and seem to
hold up fairly well (and in more or less your climate, to
boot), so with good wood choice it should be OK.

If I were to use metal fasteners
(for the legs, plus possibly pocket screws elsewhere), would those be
problematic over time?

Well, you could use Monel or silicon bronze and be confident
they'd last (and cost you a fortune), but I'd go with stainless
steel. Jamestown Distributors usually has good prices on all
manner of stainless fasteners.

BTW, I wouldn't worry too much about whit3rd's comment on long
screws. Long screws are used all over the place in boatbuilding
without issues.
