Would there be any problem if I installed foil backed fiberglass in
the wall cavity with the foil facing the interior?

It should work, but what house wrap is a radiant barrier, unless its
foil.

The one I'm looking at is hehttp://www.radiantguard.com/*Looks

My main concern was the possibility of trapping moisture between the

Normal house wraps let moisture through but not rain so it likely will
trap moisture. Why not use it under drywall inside.
