I'm a firm believer of checking clearances on stuff when working the bottom end. The only way to do that is to remove the crankshaft. The other question would be whether or not oversize bearings are available with inserts. Cranks wear too and they have pretty small journals at stock size.

Folks mention Locomotive repair shops and ability to pour babbitt. Steam engine, large industrial engine, and old sea going vessel engine repair facilities generally all have some babbit pouring capability but they do the big stuff that makes model A engines look like tinker toys. Any one can melt babbitt and pour it but a person has to have the tooling and experience to do the Ford model T & A engines. There are a lot of things to know when re-babbitting them that differ greatly from the large stuff.
