I would just pose the question, have you considered replacing the main
bearings? I am not aware that they are expected to greatly exceed the rod
bearings in longevity.
When I bought a used engine from a specialist, they strongly recommended
that I have the main bearings replaced while it was accessible, even
though it was (supposedly) a low-mileage engine. They charged $100 for
it. Even though it turned out the old bearings looked fine, I considered
it money well spent at the time. Eleven years later, "double-ditto".
Of course, I have no idea of the mileage and history of your engine, so
take it FWIW...
