I wouldn't go any thinner than OEM. I have no math or experience to back this up but it just makes sense.
I'm in the process of raising my roof also (planning) and I'm more concerned with how much overlap should be accounted for. I'm planning on overlapping the custom hat channel inserts to overlap the OEM inserts by at least 6 inches on either side of the cut.
