I have a Gentoo ebuild [0] almost working for this (I think I'm missing the step where the eln files are loaded before dumping the base image). The compile times are ... substantial. However they don't affect the development process for new code since the interpreter is always there, and I am excited to see what performance gains we will see.

From an engineering perspective this is a excellent example of a direct path from interpreted to compiled code. The trade-offs are clear (heck, they are number 0-3), and while there is complexity, all the engineering time has been effectively concentrated inside a single project, rather than forced upon tens of thousands of maintainers and users. Bravo. I wonder what other bytecode interpreters could benefit from this toolchain. Compile times from qlop.
