The NavToolbar *uses* the Navigation control -- if you don't like the
way it's used, it's easy enough to change. So there's no reason to give
the NavToolbar more options -- it's designed to be easy to configure by
subclassing.

The MouseDefaults/MouseToolbar, Navigation/NavToolbar pairs have always
been mutually exclusive.
http://dev.openlayers.org/apidocs/files/OpenLayers/Control/NavToolbar-js.html
