Kroll switch on an ARC AA or Ultra-G?

[jhereg]

I was looking at my Ultra-G sitting on my desk next to my ARC LS & I wondered about the Kroll switch. Can anyone tell me if it is feasible to drill & tap the back of either of the lights listed above and put a kroll in?

Yes to the Ultra-G.
There was one right here in B/S/T just a few days ago.
