Are these thermal pads temp conductive or insulative? If you want heat dissipation why not use the readily available thermal grease used for semiconductor mounting? Cheap and not really messy if applied correctly
A layer of Kapton (polyimide) tape would be electrically insulating but still conduct heat well enough for this application. You could then put a thermal pad under that and not have to worry about it being conductive or (I think) capacitative. I'd prefer the pad to the grease because the bottom of a PCB has lots of pointy bits that would keep the plane of the PCB spaced away from the plate, and thermal grease is not very effective as a filler material. It would also be springy enough to maintain contact with the bottom of the PCB.
I'm still not entirely sure this is a good idea though, seems like a low-temp oven for the whole tbolt would be better if you want thermal stability.
