2 genoa cars on one genoa track?

I’m intrigued about why you would leave the boom out of it.

My plan for two Genoas is boom for one and spinnaker pole for the other. I don’t see much of a downside at the moment apart from the horizontal distance it’s poled out being smaller, but if there is another flaw it would be good to know.

the boom is constrained by the aft lower shrouds so the sheeting angle is poor. A pole gives me a much better angle.

Exactly.
Also a pole is easier to derig and a boom is heavy especially with a furled sail attached.
