I have done a few... I think the most notable is the Raid Pyrenean brevet Randonneur. Anyway, I have never seen anyone with a deep carbon rim built on a dynamo hub, which was my point.
For the OP: BLB have Notorious carbon rims in 32 and 28 H drillings... 50 mm and even 90 mm if you are really crazy. Of course they are V shaped and not U shaped, so not as good as an Enve/Zipp
