I think you greatly exaggerate your need for outside help and/or the
obstacles you'd need to face when you would have asked for such help.
Quite a few of GCC developers use Emacs, so finding individuals
motivated to help with this project should not be too hard.

I suggest that you take a look at libcc1.so in GCC 5 and its use by
GDB for injecting code into the debuggee.  It might change your
perspective and your evaluation of the state of affairs, now and in
the future.
