Help:need to mod or replace two-stage clicky to one-stage

I have a Lumapower LM-303 cr123 light I would like to upgrade. Its already nickel-plated and has a seoul installed, but he stock circuit is too conservative/ineffecient. I now would like to replace the circuit with a fenix size flupic and run it on an rcr123. this means i need to replace/mod the two-level clicky into a single level. I can live with either forward/reverse as long as its single click. If anyone knows of a drop in that might work or how to go about modifying it, the help is very much appreciated,still learning.

another option might be to just replace the circuit with another with a higher current level and just leave the clicky alone. I can take measurements, just ask whats needed. btw the driver board is 15mm., the clicky 16 mm across.
thanks

Maybe a McClicky would fit? $7.50 at the Sandwich Shoppe.

Otherwise, that looks kind of like a Nuwai Q3 clickie (old ones reverse, new ones forward, but with an interruption that ruins their Flupic operation). Or get one from a Fenix. They mount on a board like that one.
