Regardless of the workaround you come up with because you have no darkroom, in the end, you'll just have negatives. It will require a darkroom to convert them to prints. I don't see any way around finishing the darkroom, and then it will be a no-brainer: trays are cheapest, easiest and best intro into 4x5. Eventually you will get into tubes and then all your problems with negatives will be solved and you can devote the rest of your life to the problems of GOOD negatives and better prints.
Meantime, ditch the Ektar ;-)
