What an odd idea. Make a super-duper LED lamp that emulates a pre-WW2
incandescent.

I think the important feature is not the shape of the filament, which in
many applications you can't see, but the wide angle of illumination,
which often works better in light fittings designed for traditonal
incandescent lamps.
