Field redefinition's help in constructing non-abelian gauge theories

Abstract
We study, using the example of general covariance, to what extent a would-be non-abelian extension of free field abelian gauge theory can be helped by a field redefinition; answer - not much! However, models resulting from dimensional reduction also include non-gauge fields to be integrated out, thereby offering a wider choice of redefinitions whose effects may indeed prove useful.
