Ok, would be interesting to know...

You should be able to unpack the binaries to different directories, and
use them in parallel as you wish.

I would claim it's even less error-prone with the way I'm proposing
because everything is statically linked, so you can never run into the
problem that one version of LilyPond finds a library from another

Feel free to try the current proof-of-concept, the overall idea of the
approach has worked on all systems that I tested so far.
