Yes, theoretically. But the external cosmetics would need to be redone in order to make the eye cover area collapse a little bit into the body.
The eye cover area is suited to allow a stock/OEM Axe detent to fully "compress" away from the marker chamber, so it needs a bit of space. Originally I was planning to use the generation-1 Mini detents which aren't as thick, but I heard they had seizing problems which is why the detent plungers are sized that large.

Here's another picture that I forgot to post...it shows the "side" of the fire body a little better.
This body has extended material on the front and back to allow for nutso cosmetics. I might have to tone it down a little bit to keep from slicing up fingers, but at least it's an option.
