John,

In fact, peer groups were not primarily designed for simplifying
configuration, but rather were implemented to allow the IOS BGP engine to
optimise CPU usage by grouping together similar peer configurations and
consequently rib calculations.  So from the outset, what you are trying to
do here is outside the scope of peer groups.
