Whist not wanting to defend G-code, which is, as you say, horrible as
a programming language, it does already contain G-codes to switch
between units and (At least with the LinuxCNC variant) repeating
patterns are reasonably manageable with the use of subroutines, loops
and conditionals.

There is an alternative (and possibly more interesting) approach, you
could develop your meta-language into an alternative interpreter for
LinuxCNC.
The interpreter doesn't _have _ to read G-code. It is just that the
only one we have does so. Pluggable interpreters have been an option
for a while.
