How worn is the flywheel? How much do you expect to need cut off of it? When a flywheel is resurfaced, both the disk surface and the pressure plate mounting surface get ground down the same amount. So from that aspect, it doesn't matter. I don't know of a minimum thickness spec. It usually doesn't need much taken off to clean up a flywheel.
But the clutch disk hub extends into the center recess where the flywheel bolts to the crankshaft, so it has to clear the bolts.
You might be able to place the bolts in the flywheel mounting holes with the heads toward the disk, then put the disk on the flywheel and see how much space is left between the bolt heads and the disk hub. Maybe use some plumbers putty to make the measurement.
I'll move your post over to the Engine forum where it'll be more on topic.
