Chainsaw Repair

We enjoyed our first Mexican sunset of the year last night. Daily highs in the mid 80s F.
Was thinking about the bikesaw and hesitant about running the drive sprocket off the rotor even with a bearing supporting it.
Tapered shaft, small key and smaller diameter then the drive side crank stub.

Both main bearings are 52mm in the crankcase so thinking about flipping crank around, build a new mounting plate for the CDI rotated 180 degrees from its original position.
Now I could have right hand drive with the original strong crank stub and retain the 11 T spur with hub and build the 13 pin rim with a keyed hub too.
I know the 2 trigger coils supposably work at different rpms so repositioned 180 degrees and timing on the stator plate adjusted....everything should work as original.
Any thoughts?
