To be honest I'm not really sure if this is such a good idea, since reds and blues feel radically different when it comes to actuation. Like, I guess it would help for streaming if that's what you want, but typing in general is going to be very strange. I know a friend who got a K60, I think, and he wouldn't stop whining about the rubber domes even if they were just on the function keys. I'd imagine the difference with the switches would probably be enough to throw off your typing. If you're fine with that, then I don't think there'll be any other issues with it, but keep that in mind.
EDIT: I just realized how dumb some of my wording sounds. Ugh, I feel so off today.
