Tagoola offers the Aura 50 UL model with a 26 mm internal and 35 mm external width, which might be close enough to what you're looking for.
Regarding the hubs, I used to always request builds with the DT Swiss 240 EXP. I stopped doing that, though, because the stock hub offered by Tagoola is just as reliable and performant while being much cheaper.
You can ask to Matter if there is something you are looking for.
