That wouldn't help a bit, because the offending capacitance occurs between the secondary and primary windings of the transformer itself (the primary being grounded).

As a side note, on some solid state sets that have the CRT heaters running off the flyback ("scan-derived" supply), you can isolate an H-K short without getting the smearing. That's because the capacitance-to-ground is negligible when you 'float' the heaters and their supply winding.
