Here's what I would do:
Buy a PCB mounted keyboard with browns, go to MechanicalKeyboards.com and order as many clears as you need for the board.
Buy Beast's switch tools from somebody on the forums, or make some yourself (lots of guides on the forums, or at least one very very good one)
Take off all the keycaps for your new keyboard, and using the switch tool, take the tops of the switches off one by one, replace the stem and the spring (or just the whole top, if that's quicker) or leave the old spring in if you want ergo clears.
While it's open, you can lube and sticker, finish up the board and you've just made your own custom creation with absolutely no soldering required.
You end up with as many browns or blues that you can sell back into the community (that's why I say browns, blues are flush) and you're set.
