I seem to remember I have done something like that, and got bitten 
hard - because it's the other way round: applied to IPv6 BGP, the
"match ip ..." stuff is just not evaluated, and vice versa.

(My map was wrong, and I had a match clause for the wrong protocol
in there, and so *all* prefixes got matched)


In any case, we have deciced to have distinct route-maps for now, and
get rid of IPv4 as soon as possible... :-)
