I had hoped to do the same thing. However reading here and elsewhere in the internet convinced me I didn’t have the skill. The head is glued on. People have been able to break glued heads with A) brute force. Wrap the head in rubber or use a rubber strap wrench and do the same for the body. Some have been able to break them loose. B) heating. Apparently this can soften the glue. Once you get it open you find a 10mm board with the led perched on top of a pedestal. This is their design for the zoom. Makes it tricky to change out the led. Sorry I don’t know about the driver. However if you can crack open the bezel you may be able to get at it. I think the prevailing opinion around BLF is that it isn’t worth the time and effort and you should just get a zoomie that is easier to mod. However I say go for it and let us know how it turns out.
