Well I couldn't take it any longer and went ahead and tried this mod. It turns out the LuxV was only using thermal grease and solder to the pads not epoxy to hold it down. That kind of surprised me. The metal disk on mine was slightly concave so I flattened it out and sanded it down some on the LED side. The thinnest shim I had was 0.55mm so I sanded it down to 0.29mm and sandwiched it between the LED and disk.
Getting the whole mess centered in the reflector took some doing but it looks pretty close to perfect. One thing I worry about with these is the thermal path. The disk only makes contact with the head at the screw posts so I hit them with thermal grease. After 10 minutes or so the head is only slightly warm, 34C. I have other lights running less current that get warmer but I don't know how to make a better path to get rid of the heat.
I was surprised it doesn't seem to put out as much light as I'd hoped. I'm using a U2SWOI and a Mag mod I made using the same LED but only ~500mA smokes it. I'm guessing the larger Mag reflector is what makes a lot of difference. Part is also partly perception since the Mag has a very noticeable hotspot but the KL6 has a much softer hotspot. One other thing is that I'm running it on 2x18650s not 3xCR123s.
