Would it be legal and possible to use 3/4" conduit to carry two 4 ga

Nope, (except if you use imc conduit), but you would be much smarter to
use 1" anyway - it would be an easier pull.

Yes. The trouble is, I already have 3/4" conduit in place.

Well then, you need to recalculate your load and see if you really need wire
that big. My instinct tells me I'd be willing to bet you're not doing
anything requiring more than the ampacity of an 8/3 or possibly (remote
chance)a 6/3 feeder, but of course i dont know your load or what you are
running out there. Again, my advice is to take a hard look at the loads you
plan to feed and see what you really need for a feeder.
If you are willing, post here what your plans are and we can give you some
feedback - maybe its a smaller job than you first thought - then again,
maybe not....
