Patrick,

Yes, that should work provided the output current of the lower voltage xfrmr
is  high enough to power the NST, even at lower voltage levels.

A 15/30 Franceformer NST draws about 4.25 amps without correction caps at
full input voltage, 120vac. So your 60vac xfrmr will need at least 3 amps
output current capability to include a good safety margin.
