L1 switch on L4 body?

[Icarus]

Is it possible to use the SF L1 switch on an SF L4 body + KL1 bezel? Then you get a KL1 with two levels of light?
Two levels of light and two times the runtime of an L1, this would be the perfect EDC for me.
Does the L1 bezel also runs on 2x 123a batteries?

No, the L1 switch will not work on the L4 body.
Yes, the KL1 bezel will work on the L4 body.
No, the L1 bezel should not be driven by 2-cells.
