BigBear,
The only requirements you may see are between winpe and missing drivers for the tablet. As long as winpe can see the drives and connect to the tablet then GSS should be able to image it just fine.
See the below articles on locating drivers, remember if you have winpe10 that you will be acquiring windows 10 drivers to match the tablets hardware. Also see the below link on GSS compatibility with surface pro tablets, this may give you a little more information on working with tablets and GSS.
