No, that would break compatibility. You need a new codec. That's what
we're working on, but it will take time (and probably not replace Vorbis
anyway).

There's a 37 kbps mode, but it's only does something decent for speech
(quite bad on music).

It's very crude, there's mode1 (37 kbps) and mode2 (57 kbps) that you
can use (and mode3 doesn't work). Don't worry, it's not intended to stay
like that.
