The WFS protocol allows multiple feature types to be queried in a single
GetFeature request, e.g.:

http://localhost:8080/geoserver/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=sf:archsites,sf:roads

This will make for a single WFS request (which I don't know if it's
possible to configure in OL)
but mind, GeoServer will still do two separate SQL queries to build the GML
in output

Cheers
Andrea
