Looking at that setup IMO you've got the ideal conditions for a 24-1 or 36-1 toothed wheel to go in place of the stock trigger AND then you could adopt the second trigger VR sensor for a cam sensor.
You can even measure the gap between the rotor and VR sensor for the cam sensor.
If the XJ600 cams are anything like the other Yamaha cams that I have seen from the period then the cam gear is bolted to the cams in the middle.
Get fractionally longer bolts and make a dished wheel with one or two teeth for the exhaust cam that's bolted on with the cam gear that runs outside the chain and close to the cam cover- then you only need a small hole in the cam cover for the trigger.
It's more work initially to make, or have made, the trigger wheels however I think it will be simpler in the long run and improve accuracy of both ignition and injection systems.
