Okay, let's do that ... only one of five Campy wheels that are available in both rim and disc meet your claim of "rim brake versions are easily 100g lighter."
Bora WTO 33: Rim 1395g, Disc 1485g (diff = 90g)
Bora WTO 45: Rim 1496g, Disc 1520g (diff = 24g)
Bora WTO 60: Rim 1547g, Disc 1590g (diff = 43g)
Zonda: Rim 1540g, Disc 1675g (diff = 135g)
Scirocco: Rim 1755g, Disc 1739g (diff = -16g)
