The number of contacts will be a challenge, as well as the size of most ag-1, up to M-25 flash holders.
Flashbulbs hold their light output in the form of wire ready to be oxidized inside the bulb.

A small priming charge, made to ignite from the glow of a filament heated by current from a single pair of contacts.

Electronc flash has it's energy stored in an external capacitor, fed from an oscillator circuit.

he flash tube has two main contacts to discharge the main current though, and a trigger band that is fed from the firing transformer, which kicks a brief high voltage to the trigger band.

The trigger band causes the electric field potential in the area to rise, thus ionizing the gas mixture in the tube, allowing the main flash charge to discharge as a result of the ion electron current.

So for electronic flash you need three contacts to the flash tube.
