I really like the Yamaha Alain Trudel piece. I would like to play it on my medium bore horn as well. Unfortunately there is no small shank version of the the Trudel piece.
I really like the rim, the feeling and sound of this piece. Are there any small shank options out there, which are similiar to the Yamaha Trudel?
I know of only one. I once had a Trudel rim threaded to fit a Yamaha 51 cup. There's a slight step where they join, but not much. It seemed to play fine. But I never played it critically. I was just trying to avoid switching rims, which I've never liked. I eventually went to a Doug Elliot system.
The rim threads onto DE LT cups just fine, but there's a small step because the LT diameter is too big. Maybe MT would work better?
It can really be a killer mouthpiece if you like 6½-ish sized mouthpieces!
Might be possible to get one custom-made by Yamaha in small shank, though that might cost you. If not possible, then I would say send it to Vennture for them to scan and copy in small shank. Otherwise could have your leadpipe pulled and replace it with one that will take a large shank, but also costly and will change your horn.

I second the Vennture route, but care must be taken with the backbore -- going from large shank to small shank will almost certainly require a change to the length of the entire mouthpiece and also almost certainly require a less open backbore (if only to fit inside the smaller shank). You can do that in the software, but you might want to start by extrapolating one of the small shank 6.5AL backbores they have in their database as a starting point.
I'd scan the original and have that pulled up, then pull up Bach's 6.5 SS, copy the cup of the Trudel, and copy the backbore and shank tip diameter of the 6.5 (it will likely need truncating or extrapolating to mate with the different throat size). Make sure the overall length is set to mimic the 6.5ss. Then, possibly, I'd do deep editing on the backbore in your design so that the backbore is in between the Trudel and 6.5 profiles, particularly in the throat length. You may still not wind up with something that is comparable.
Somewhat related, but funny. Yamaha Canada's artist page for AT Shows him holding an alto trombone that they don't sell any more, and that obviously can't accept his signature mouthpiece.
I know of one deep funneled 6 1/2 sized that I liked for some time : the Stork BT6 : https://storkcustom.com/trombone/
Available in both large and small shanks.
