Shaun,

this method may be good for raising the Q, but it probably
won't increase the spark length.  This is because the wider
diameter secondary has more capacitance, and forces the
use of a smaller toroid, for a given input power.  This tends
to reduce the total spark length, or at the best probably 
won't help.  I'm assuming the coil was optimal to begin with.
