I'm sure you know whites make more sound than browns. I'm not talking like, the difference between a dead silent room and a rock concert, but there is def a difference there, if you look for it or just use both switches so often, you can tell the slight difference (as i do).
and making ergo clears would prolly be cheaper and more of a custom mod alternative than buying a new keyboard, heck, ergo clears aren't even sold, and a good old cherry keyboard with white switches should run 20bucks or so on ebay (mine did to harvest whites).
