See the 3 HV rects in this circuit? They constitute an HV trippler. Saw off the third HV rect tube (and everything right of the second HV rect), and you have an HV doubler.

There were also SS HV doublers, tripplers, and quadrupplers in 70's SS color sets that could be used if period correct look is not a concern.
Any doubler will increase load on the flyback and reduce width....Monitor H Out tube cathode current and flyback temperature over an extended test run and if it gets excessive power down and try something else.
Tube doublers will draw more power due to the tube heaters.
