The 3D files are great, but I don't think any of their 3D models are all that bright, even the Slim bari, which surprised me, and which I absolutely love. They just released a new model, the Power, that might work, and I'm assuming the files will be available soon, but their first mouthpieces were stainless, and much like the Atti mouthpieces, I always wanted to try them, though I wanted the darker of the two models. The Plus seems like it might be what you're looking for.
Also, for Saxscape, in addition to the Downtown MB I the website (saxscape.com) describes his "Red River" model thusly:
"Huge bright sound with a large chamber, the next level from a Berg Larsen." I've never seen one in the wild, but I'm sure he'd make one for you.
Not sure how tariffs and fees would affect your ability to purchase from him, but it's a thought.
