Alright, so I put together a plan for a Maglite host.
–2D Mag
Custom milled bezel (replaces the stock head and threads on to hold the module in place, like the one shown here 3D Magmule with triple Nichia 219s)
-Custom heatsink that rests on top of the switch housing and rises just outside the mag body for the module to mount to
–3 x 26500 IMR cells
Cost to put all of this together will be around $160. Way more expensive than I wanted, but it will be a nice light
