I agree with you.

I would "roll in" (install) a new set of mains and rod bearings.
To be safe, and for peace of mind, I would plastigage the clearance on all of the new bearings.

I had a freind who owned a BMW 325, and one night (after having a few too many), ran off the road and hit a culvert that was just high enough to fracture the cast aluminum oil pan and break the oil pump off the engine.

Being too drunk to drive, he proceeded anyway to continue on home, which was about 5 miles.
The next morning...still partly drunk, badly hung over and not remembering what had happened, he started the car and noticed the oil light on. He checked the oil, and finding it empty, poured 3 quarts of oil thru the engine and out onto the ground.....which he also didn't notice.
He then proceeded to my shop (which was another 8 miles) where I realized what had happened.

He asked me if I would repair the engine, and I said I "only if I don't have to pull it"

I removed what was left of the oil pan and removed the Main bearing caps.
The journals were shiny and still looked like new.....I couldn't believe it.
I pulled the rod caps, and they looked the same.
I then pulled the valve cover and inspected the cam journals.....No apparent damage there either.

I came to the conclusion that breaking the oil pump was the only thing that saved this engine.
If the pump had continued to operate while dry, it would have blown all of the oil out of the crankshaft and out of the bearings.
Since this did not happen, the oil film that remained lubricated the crankshaft, and cam bearings.

I went ahead and installed new standard bearings (which I did plastigage....every bearing clearance was within factory spec.), installed a new oil pump, and got a used oil pan at a salvage yard.

After I got it back together, the engine fired right up and ran quiet with good oil pressure.
The owner drove the car for about 2 more years before it was sold.

My point is to go with what you can see and measure, and not on what should have happened.

Just my opinion
Hope this helps
