Something similar certainly works with electrostatic generators. I fix a 
small ball to the main positive terminal with a short section of plastic tube,
and get longer sparks than with the main terminals alone (in a Wimshurst
machine, for example). But almost the same effect is obtained with a
direct connection, and the trick works only with the positive terminal.
I don't know what would happen in a Tesla coil. Someone coild make a test.
