This isn't going to happen any time soon, for several reasons. :(

You explained why yourself. This issue can be solved doing something
like what is done for python, compiling and installing bytecode for
each interpreter, but unless someone implements this perfectly, at
least luajit isn't going to be involved in such thing.

No, this is a real problem to implement multi-interpreter support.
They don't care about the issue because they don't care about
supporting other interpreters, or even multiple versions of Lua
installed in parallel.

I'm going to repeat this once again: Lua was designed to be built
statically, then upstream don't cares about compatibility between
different versions and interpreters. Creating static libraries is
something that distributions want (and is generally the best
approach), but the upstream developers don't care about this at all.
That said, if you want to go that way, you are in your own, upstream
isn't going to care about your issues or make your life easier.
