I'm at the same stage as you, finding it an excellent learning experience taking on a first build. Thoughts...
1. decent 2 bearing crankcases are still moderately available and comparatively cheap, so consider the costs of fettling yours in relation to just finding a better one
2. if your three bearing engine is a later one that has good c/case, rods and shell bearings, it could be worth doing that one properly as it will reduce the hassles of white metalling.... and give you a good contrast between your two engines.
