Having said that (and looked at the script's guts), it doesn't look trivial
to do ;-)
However, running gcc_select with the -n flag gives you all the steps and you
could build your own gcc selector/switcher, instead of hacking on the system
script.

[/Users/paul]:: /usr/sbin/gcc_select -n 3.3
Commands that would be executed if "-n" were not specified:
  mkdir -p /usr/bin
  rm -f /usr/bin/cc /usr/bin/c++
  rm -f /usr/bin/cc.real
  rm -f /usr/bin/c++.real
