So Vulgano has done it too. I modified an obscure mouthpiece I got in one of my trumpet acquisitions from ebay or pawn shop. Thanks to the Conn Loyalist I got the measurements for a long shank Cornet mouthpiece. My band saw cut it to lenght. I opened the diameter of the throat with a drill bit. Sculpted the cup and rim edges with sandpaper until I liked the feel on my lips, and finished the project off with some jewelers rough and my conical buffing wheel. Lots of fun, and it works good too. I'd say more, but I've got to meet a buddy for coffee, and a little bragging................

Yes I did. I opened the throat of a Bach 7E mouthpiece in steps until I could almost climb through it. I documented the intonation, slotting and playability, at that time on my Bach 72*ML Bb and 229H C. Each step got worse until it was unplayable.
I also tried to change the inner rim size of an old holton cornet mouthpiece - the results, my lips turned green when playing and I ended up buying a real cornet mouthpiece.
I also opened the throat of my natural trumpet mouthpiece. I had some intonation issues and was in fact able to solve them with no other comprimizes in playability (I got lucky!)

Gosh yes! I have a friend in Iowa that chucks the mouth piece in his lathe and we bore, shave and trim. I usually do it with an old model like a MF3 or 5SV. I did bore out my 3D to the next larger size. I think it is a 26 drill? I blow the trumpet in his basement and we destroy mouth pieces. Lots of fun.
