I've got new R600 levers with single button hoods, but an older SM-6500 bracket/sensor kit, made for the two-button right hood. What is recommended: shall I get a new bracket/sensor kit for single-button hoods, or shall I instead try to fit a two-button hood on the R600 lever?

Neither. Just install it and ride.
The "buttons" in the hoods are not functional, they just serve as a tactile indicator of where the actual buttons are.
Before I switched to Campagnolo, my Hetchins had 105 brifters with the both-buttons-on-the-right rubber hoods, but with the one-button-on-each-side hardware, worked just fine.
