By spawning an additional monitor terminal, but switching off its
readline support (as that is handled by gdb).
In case there is still someone out there not being aware of this ;) : we
_do_ have support for multiple monitors in qemu already. Just try
"-monitor X -serial mon:Y" with X!=Y.

Proxying would mean interpreting all "classic" monitor commands to catch
those that may interfere with the mgmt app state. I also don't think
that is worth the effort.
