I know this is a month old so I don’t know if anyone will see it, but I have had stuff like that work. When I got my berg larsen metal tenor mouthpiece, I really wanted to try it, but I only had my bari with me. I played it and it sounded awesome! Made me really want to get a bari metal mouthpiece, but I can’t afford it.. It made a good sound, but it was really sharp, so I wouldn’t ever normally do it. It works alright though if there’s nothing else to use.
