Works, specially if the toroid has a small central hole and is covered, 
with the upper roller and charge collector close to the top cover. 
If the hole is too big the shielding is poor and the attainable voltage 
is small. An interesting idea may be to just mount a toroid around, or
over, a small VDG sphere. It would allow the accumulation of more 
charge and the production of more intense DC sparks.

Because a regular VDG charges up slowly, and charges that leak have time
to go away and don't return. A Tesla coil charges the terminal fast, 
and charges that try to go away through a breakout point are pushed 
back and forth by the RF, forming bright streamers.

It would be difficult to make an effective rectifier for RF signals at
high voltage. More probably there will be no difference from the
regular operation of the coil. Charges that manage to escape from the
terminal through the ion rectifier will continue to be pushed by the
huge RF electric field, and will form streamers anyway.

"Ask Nature", or, make experiments.
