Sorry to disappoint you, but this job is being done on my driveway with limited funds. No shop, no extensive knowledge, no experience.
I took the pistons off today after using a ridge reamer to ensure that the rings didn't get caught and break. It seems re-ringing will not do. The end gap on the new rings is enormous (~.031 vs recommended .007). At this point, it seems my only options are to do an engine swap, take this block to see if it can go .080 over, or sell as-is. I'd appreciate any input on the first two options.
