That's great. I was worried you may have gotten forgotten.
now that shimano makes hydraulic di2, others should have a pretty straight forward option. You could put a bar end tt shift lever (front) on the needed side with the normal sti lever (rear) and the only special part you would need is the brake splitter. They even let you reprogram which shift lever does which so left vs right hand shouldn't manner. The limiting factor would be disc brakes but even that is pretty common now.
