I don't think that kind of a distribution would be a good thing at all, especially if those are stock clears.
I've been on the following hybrid combination of switches for the last six months using clears and browns, but the clears have been modded to ergoclears.
original distribution:

current distribution:

As you can see, the clears are on the alphas, and everything else mod related has been done with browns instead. I find that mods with ergo-clears aren't optimal, given that such keys do not benefit from additional tactility, and in some cases, can be a little jarring to use; these are keys that you hold down and release, while the alphas are the ones you strike. the additional tactility is mostly beneficial for keys you strike and release rapidly, ie. in typing. a huge tactile bump is a little jarring for button that you press and hold from my personal experience.
swill is spot on with the distribution for browns and clears imo.
You do not want a huge variation in the force requirements on the same board. either go ergo clears, or use clear springs in brown switches.
