It looks like the clear plastic tabs could be pried away from the lower part of the casing if you approach it from the underside, but then you would have to remove all the switches from your board.
Going off the pictures from a quick google image search, unless you have some very skinny tools to go into the top part of the casing through the four holes on each side, there is going to be no way for you to open them up without disassembly.
That's what I was afraid of. I'm not sure it's really worth the trouble then.
Scratchiness aside, what do you think about the low profile switches and caps? I look at these from time to time and wonder if I would like it.
They are pleasant. The sound is nice. I went from working in my own office to working in a team room, and I always felt bad for using my Model M, but I don't feel self conscious using this. I'd say it's the least obnoxious sounding clicky switch (in terms of annoying other people). I compare it to the sound of Rice Krispies cracking when you pour milk on them. The tactility is rather low and hard to feel without the sound (if wearing headphones or something), which is generally when the scratchiness is annoying since it becomes more apparent. Stabilized keys are really good, very stable with no rattle.
I like regular Box Navies so much that I thought about getting NovelKeys's low profile pale blues to stick in this, but didn't feel like paying 50% of the keyboard's cost on new switches (and having to desolder).
The keycaps remind me of a good laptop, like an old Thinkpad. Too bad there aren't any options for replacements.
