A 27x1-1/4" (630x32) tire would supposedly have the same diameter as a 700x36C (if they made one).
The brake pads would have to be able to be adjusted 4mm in the caliper if used.
But to be clear, it's the 4mm difference in radius that would make the difference in ride height, not the 8mm diameter. Again, sidewall height of tires being equal-
