I think this came as no surprise! Rebuild definitely worth your consideration. I'd do it if I had a nice heated garage.

I've started to think about it...
Today I took the bearing carrier apart to inspect the crankshaft. The main bearings beside the #2 piston are toast... all the others look good. The crankshaft journal looks OK. The big question is if the journal for the the big end of #2 is beyond repair. It is lightly scored, enough to feel it but not enough for a fingernail to catch on. I'm going to have to take it to a professional for an opinion.

This photo of the big end journal is not great but you can see the scoring, it looks worse than it feels. The main journal on the left is the one that has fried bearings.



Here is one of the fried bearings. The bearing carrier seems to be fine when the offending bearing is removed.

If the scoring is not too bad it may be polished out and the clearance may still be within spec. The conrod is probably to be replaced if the bearing has spun inside of it. Sometimes you can find the crank-bearing carrier assembly for cheap on ebay, as an alternative.
