Alright, so I hacked my mouthpiece to acceptable functionality with a standard stem with the silicone sleeve. Basically, I carefully wedged it into the mouthpiece making sure that only the sleeve made contact with the mouthpiece. This is one of the later, thicker stems. Just tested this, and hell yeah, this is a great piece.
@cybrguy this may be a fun project for your broken one if you're into that sort of thing. From your picture, it looks like you could DIY a whip to the can with some aquarium glue.

@Trogdor's discussion, I'm thinking I'm going to love this setup.
