Yes, that could help.
But I would think one must be very careful doing that since it's an AC
circuit and current will still flow. Since coiling uses tranformers with
ratios at 1:100 or better then even a small amount of current flow can
result in a dangerous voltage level at the secondaries. If one were to use
one it'd have to be fairly small as Marc M. measured in another thread,
.0005uF. If too small then it's probably not going to do much good. If big
enough to do any good then the resulting constant current flow may be too
much for safety as seen at the secondaries.
