No, you will need a regulator/rectifier with extra input terminal.
Each output wire is coming from a different coil, as magnet passes them it creates a voltage pulse one way, then when when it passes other end, creates reverse pulse.
If you 'common' two stator coils you will get two potentially competing voltage pulses on one wire, and the regulator probably doesn't have the current carrying capacity to handle both coils power; which was why it was run AC direct to the tungsten bulbs.
Count the number of stator output's and find a regulator to suit.
I am 12v converting my DT and fitting HID to it, I am using a 12v C70/Pit-Bike 'two wire' regulator/rectifier, good for about 10A I am told; £10 off e-bay.
Not sure about a one wire rectifier, for the head-lamp circuit alone; you might get away with a two wire reg/rect, and wiring your single input to both pins; but you will want some charge damping on it, either a small battery of big capacitor.
Using a reg/rect with an extra pin on it that would take the light coil and use it to charge battery probably the better way of doing it; but think you'll have to trawl wiring scematics to find a bike that has similar charging arrangement to what you want and similar power magneto.
