Propellant cross-feed? Would it make the same change in payload
capability as Falcon 9 Heavy compared to Falcon Heavy (65%)?

I would think it would be very costly to attempt to do that with LH2,
which would make a cross-fed D-IVH even less cost competitive compared to
Falcon Heavy, even if higher performance.
