I've been holding on to a Fenix Flupic for several months now. When I first got it Seouls and Crees weren't even out. My original plan was to pair the Flupic with a UXOJ. But several projects kept me from making it happen. I've been very busy modding light for other people lately so I wanted to do a little project for myself today. 
Anyway, with the emergence of the Seoul LED the orignal plan for the LuxIII was 86'd. I figured the Seoul would make a great candidate for the mod. So I decided I'd give it a go.
First I removed the stock emitter and driver. No problems here, just de-soldered at took them out. The emitter popped right out after the added heat of removing the wires and leads.
Next with the lower die height of the Seoul I had to make a .030" disc to raise the emitter for proper focus in the reflector. More on the reflector modification in a mintue.. So I turned a .030 disc from aluminum on the lathe. I made it just under the diameter of the pocket in which it now resides. It was anchored in place with Arctic Alumina epoxy.
After the disc was set I installed the Flupic..
Then I AA epoxied the Seoul P4 emitter to the disc being very careful to maintain a layer of epoxy between the slug and aluminum disc. Once the epoxy set I soldered the leads to the board.
On to the reflector. I popped it in the lathe and turned a pocket in the underside to allow the LED to move up into the reflector for proper focus. This made the hole slightly larger but really doesn't matter.
As you can see I got it centered pretty nicely.
I have the reflector and LE installed in the head. However the best test I can do at the moment is to hold a 14670 in it and make the - contact with a wire between the battery and body. I've got a 14500 on order from David at the Fenix store so hopefully I can post some beamshots in a couple days.
Depending on what the beam looks like I may experiment with a McR reflector and maybe even make a custom heat sink too.
More to come...
