I think the biggest difference is that a normal GFCI will not work very well below the rated voltage, so being on the output might be problematic.
I would think a decent isolation transformer would get rid of the fluctuations driven by the load in the VAT draw. So 1/1 isolation transformer on the line, and then the VAT plugged into that.
If everything is grounded properly the GFCI should still serve as protection, even if the problem occurs in the ultimate load, as the imbalance will show up back at the outlet.
