What we do in GeoServer is to apply a visitor to the filter:
https://svn.codehaus.org/geoserver/trunk/src/main/src/main/java/org/geoserver/feature/ReprojectingFilterVisitor.java

We can move that class back to Geotools.

Yeah, the filter implementations are one of the oldest pieces in 
GeoTools and... well... it shows, could certainly use a cleanup
