I have no experience to share, but will follow your proposed experiment with interest.

I'd hazard a guess that in the relatively unpressurized Photon, the white gas will be sooty. This in itself may make it unsuitable.

Have you considered carrying some Esbit tabs and a folding or wing stove for them? You could rationalize them as backup firestarters or a safety margin in case your white gas estimate is a meal off.
