would a gcc by any other name still smell?

Use different paths for the two compilers.  e.g. configure the egcs
compiler as --prefix=/usr/local/egcs , and then if you like, say

ln -s /usr/local/egcs/bin/gcc /usr/local/bin/egcs-gcc

Beware -- the -V switch isn't going to work if you're also trying to
switch between two different versions of the C++ library.
