I've thought about your making these kits and what a pita it could be, especially if you put in some hours at work. I'm sure molding and cleaning the button castings (especially the MK2,) assembling the kits, and mailing them out takes a bit of time. If you could ramp-up on volume, then it might be financially rewarding; however, you will likely have to settle for the modest dollars knowing that you have made me and others very appreciative of your labors. Aside from the cosmetic improvements, I drive daily to/from work in the dark, so the illuminated buttons are fantastic.

BTW, while I have both MK2 and MK2a players, I'm sure you could save yourself some time if you only provided a single knob in your kits.
