Here's my disc mounting system using sprinkler hose and stainless screws around the perimeter. The hose ring is rigid enough to stay in place on it's own, but cut a few mm too large is stuffed tightly into the recess.

Just short of 36 lbs is what I got for the front wheel. Safe to bet on 38 for the rear. Could be lighter, but not much. I suspect that dropping to the 19" wheels would carry a Crr penalty though, more than cancelling out any weight reduction.
