As a rule I don’t recommend carbon clinchers for rim brake applications. Carbon clinchers for disc brakes are a different story. Check out this recent build of carbon rims to Hope hubs:
Blog: Hope Pro2 Hubs
These are sweet 29er race wheels but great fun in general, especially on the climbs. The Hope hubs were the customer’s own and I supplied Stan’s Crest rims and Sapim Laser spokes. With aluminum nipples they add up to 1615g, that is 732g front and 883g rear (DT Swiss 240S hubs would push it under 1475g total). Because of the rim weight and resultant low tension ceiling, build quality is extra important on a wheelset like this. These wheels were built with tension balanced to ±7% or better. In getting there both wheels were stress relieved multiple times, which causes tension to relax so I can bring it up as much as possible. Lateral alignment is nearly perfect with a 0.1mm rise at the decals being the limiting factor. Quality takes time and attention but it pays dividends.
