Well...

Mere minutes after I sent this email, I discovered that there was already a 
project that I had missed, doing something almost but not quite similar,

https://pypi.org/project/lilyponddist

The “not quite” part is that it does not bundle LilyPond, it downloads it 
(always the same version) the first time the module is imported.
