I was hopeful, but, unfortunately, this does not scale up very good.

Our model M-50 coil which puts out a 56 inch long spark, using your 
value of 139,000 volts / 7 inches at 120 pps, would be developing 56 
inch x  (139,000 v / 7 inch) which equals 56 inch x 19.857 kV / inch 
at 120 pps = 1.1 megaVolts!

I would estimate based on the 70% x Vpri x SQR (Ls/Lp) the real 
output is around 220 kV and not 1,100 kV.

A large differential.
