I've tried a mod on my Ultrafire C3 SS from DX (sku.26122). Wonderful flashlight for the money, but mine had a greenish q5 and a very ringy beam. Also, I wasn't using it anymore since I got my 5 mode akoray/nkoray (same driver but I got a better tint).
For this mod I used KD XPG r5 on 14mm board, which perfectly replaces the original Q5 board.
To remove the original star I left the head into the freezer for 6 hours. After this treatment the glue snapped easily twisting the board with a pair of screwdrivers.
When reassembling the head with the new board, I applied good quality thermal compound in place of the old bulk one. Also, I used an alu foil to fill the gap between the reflector hole and the led die. I found out that this easy workaround noticeably improves the beam pattern.
In the end, the flashlight lost a bit of throw (I'm not even sure about that because although the hotspot is a bit larger, the increased brightness compensates this) but gained a much better beam pattern. I really like the result and will try the same mod on the Akoray as soon as I get my hands on another XP-G 16mm board.
The XPG soldered:
Everything back in place. Notice the thick alu foil filling the gap around the led. This part is insulated with a thin layer of tape between it and the top of the board:
