I like your overall idea, but there are a few problems with it.
1. Multiple copies of libraries can be really annoying.  Take the
OpenSSL library and it's trusted root CA list.  Maintaining several
lists is not fun.  
2. It will make your $PATH env variable really really long.  Unless you
want to specify full paths to every command you run.

You can try other distro's which handle package installations of
non-default versions better.  IMHO, Debian based distros handle it a
little better, due to the stable,testing,unstable branches.  Gentoo
handles it much much better due to it's source compiling nature.

However, my overall advice is to just install the non-default version
from source, then upgrade it to the binary package when, or if that
becomes available.  In general, the times where you need a version not
in the default repositories is rare enough to not have to start a whole
new package management philosophy.
