Others can chime in on whether or not this is feasible, but I can have a couple spare #2 main caps in my parts stash and will give you one if the machine shop can use it to salvage the block. The other three sound as though they are good, so perhaps you can install one of my extras and the shop can line bore it to match the other three without cutting any more metal except from the replacement #2 cap?
I have never had a block line bored, so I'm flying kinda blind here. Those of you with more machine shop experience, please weigh in. If this could fix 51cowboy's problem. I'll gladly donate a #2 bearing cap.

You just take a few thou off the mounting surface of the cap, torque it in place, and then bore it.
