Can we run two of the same Summoner spell's and get 50% cooldown reduction?

I thought it be a cool idea to make it so you can use two of the same summoner spells and get a 50% reduction in cooldown time.

Heres what the summoner spells cooldowns are set to now.

Barrier, cooldown 210sec {{summoner:2}} Clairvoyance, , cooldown 60sec Clarity, cooldown 180sec cleanse, cooldown 210sec Flash, cooldown 300sec ghost, cooldown 210sec heal, cooldown 240sec ignite, cooldown 210sec smite, cooldown 60sec teleport, cooldown 300sec

The only real issue with this is Smite do to a 30sec cooldown and the new abilities it has makes it a little more OP then the rest.
