I finally sourced some MuMetal cans that are big enough to house the SUT's. Two of them will fit together to house a pair and a band of adhesive backed mumetal holds them together nicely.
While not exactly small it goes a long way to getting the required shielding to package these things up. Simply add a steel box, some RCA's, solder and enjoy.
