Ice/Rock is a big NO screaming at you D:
It'll have a 4x weak to Fighting and Steel, a 2x weak to Water, Ground, and Grass, and only resist Normal, Flying, Ice, and Poison, ffs. They don't really grant that good coverage together either, with Rock's real few benefits over Ice being the ability to hit the Fire and Ice-types SE, and Water-types for normal damage. I mean, would you like to create a thingy that screams "Scizor bait!!!!" ?
As for the topic, I'm proud to say that my favourite poke actually removes some of the water from the game by evolving - go go Masquerain! (:
