Yes, all BT wheels through '54 (no shovels)can be made to fit, with scraper alterations. They are heavier than your pre-war units though, so you will lose performance for a light solo machine, but gain some torque for a heavy ol' Lady payload. Ideally you should look for some flatty (U)wheels, as they are the same original diameter, but a healthy stroke. Note:I like my 61" lowers with 74" upper ends just fine. One is close to 70" anyway.
