Sounds like a plan . . . you probably saw my YouTube video on bearing setup.
If you're just trying to keep it on the road a bit, then maybe buy just one rod. Yes, it may be out of balance a bit, but in the short term that will probably be okay. One thing to do is to take a close look at good rods and mic the big-end bore. Then mic the crank journals. Sometimes folks would bore/hone the rods and use oversize bearings in both the OD direction as well as the journal direction.
