I have a few 33P X-D rims here.
The price isn't much more than the regular-depth rims.
An enthusiastic tubenetter ordered ONE, never responded when I let them know it had been produced , and (well...) when it was produced for them, we went ahead and produced a couple of additional ones "for stock".
They're apparently Dave's interpretation (not a "Sellmansberger-design" rim, but fits all "Sellmansberger-design" cups) of a PT-50/PT-88 type of rim.
Again, these are the EXTRA DEEP version...so (potentially) you could convert your "regular-deep" cup blokepiece to something (well...) extra deep (again: like a PT-50 or PT-88 feels-against-your-face mouthpiece)...except (perhaps...??) better than those.
EDIT: also found that I have SEVERAL of the MOST POPULAR #2 33.2mm rims in the "Profundo" depth...as well as several others...including the other two diameters of #2 profile rims
