I suggest you discuss any GCC development ideas on the mailing list
gcc@gcc.gnu.org

As far as RTL compression is concerned, I do not remember it being
discussed or proposed before.  From what I can tell, we are not usually
looking at RTL memory footprint when dealing with excessive memory
consumption, one reason is likely that there is only one function in the
RTL representation at a time, as opposed to the whole compilation unit
in GIMPLE.  Others will surely correct me if I am wrong, however, and
may even suggest other areas where compilation speed could be improved.

Thanks,

Martin
