impossible to accurately answer without potentials, but generally yes. You seem to have enough depth in the front and backcourts so that the young players won't be needed necessarily so taking one out of the rotation shouldn't hurt. From there look at the potential of the players and future class structure (especially as regards bigs and littles) and if applying redshirt helps balance classes a bit (or stack them if that's your preferences) or give a lower WE player extra time to try to hit his potentials (or for a future pg especially to have a little more time for IQ development) then go for it...
