Yes, but jwmckenzie is generally correct if your total power requirement is unchanged when switching to 12V.

For example, it you have a total of 60 watts of power requirement on a 6V system, the generator has to provide 6 volts x 10 amps = 60W. Converting to 12 volts, if the 6V light bulbs are replaced with equivalent power 12V bulbs (and the coil), the total power requirement will still be 60W, and now the generator will need to supply only 5 amps; 12V x 5 amps = 60W.
