There are people other than you who do that?

Yep,bucket loads,was a very common method of achieving a fire lighting effect in theatre and film

Any potential problems there? Each string is rated at 33 watts, the linked adapter is 300 watts so should be fine.

There might be a sight imbalance when cold starting as one string is likely to have a series resistance lower than the other two. And one string might be brighter just because of the bulb rating, but in theory, it work out okay. Let us know how you get on.

   I enjoyed experimenting, with individual mini-lamps, although I didn't consider the issue of self-shorting types...(Yikes!).
   One curious phenomina that occured was a variation of lamp 'HALO' visual trick;  Somebody had built a room decoration where a little red bulb was positioned precisely in front of a blue mini-bulb.  The trick effect was that the red mini-lamps appeared to have a BLUE aura!  You had to move your head around a bit, to discover what was going on.

Wouldn't hurt to downgrade the volts, some, using 2.0 volts vs. 2.4 standard.  Don't forget that's AC rms, in those 'old days' (1992).  I think the current was somewhere around 40 to 100 mA each, which is a fairly fast drain, on small battery...certainly won't last more than one night.
   Some guitar effects, such as Fender amp tremolo have used the softer response of a filament lamp / with LDR (light dependant resistor), for modulating volume.
