See, for example, Arnold, Falk, and Winther's 2007 paper on mixed FEM
for elasticity with weakly imposed symmetry.  It's the usual H(div)
methodology and should apply equally well to Stokes.  I'm not aware of
any analysis or results of choosing quadrature to eliminate flux terms
in these discretizations.
