Is there anything out there that is substantially less than 400g, >20mm internal, and tubeless? Depth isn't really a concern. There are tons of mountain bike rims that fit this, but are all hookless and not really able to hold even low road pressures while tubeless.

The Nox Composites Citico might fit the bill.

Oh man, Nox Composites was the first place I looked but I completely missed that one because I figured the road rims would all be lighter.

The BDop DTO-40 rim could be an option. Miller says his weighed 410 grams/each. Much cheaper and deeper than the Nox wheels but not as wide or quite as light.

Edit: Sorry, only 18mm wide internal.

pressure limits apply to the MTB rims though. Also the really light rims are not that stiff so you have to use stiffer heavier spokes or more of them which kind of defeats the point to me.

Hoop stress goes down with smaller tire sizes, so you could probably get away with higher pressure for road tires.
American Classic rates them to 28c tires: https://amclassic.com/index.php/downloads/dl/file/id/50/product/0/recommended_tire_size_chart.pdf

Yes :) (but that was not the question...)
