Being lightly frosted with a regulated driver it’s probably not a huge benefit to slice this one unless you just don’t like the existing beam.

With a FET you can still bump up the output to compensate for the lost lumens (assuming you aren’t comparing turbo to turbo). Being frosted will diminish some of the throw from the slice. The better play may be to replace two of the LEDs with 3000K emitters if you want to change tint.
