choombak,
I don't know how difficult it would be to remove the led assembly from the sealed bezel. IMHO, The best solution would be to get ahold of an 'empty' Z44 bezel on the marketplace, unscrew the sealed bezel, put the Malkoff unit in the empty bezel, and screw it on. That way you would have either a spare 'KX4' you could possibly put on another body someday, or you could trade/sell the KX4 on the marketplace.
