Funny thing is in the Ewok movies/cartoons of all places Endor (although it's a moon) is shown to have a desert and several mountains (including a sentient one).
I suppose it could be argued that Earth itself was a "water world" during the Archean and an ice one during the Cryogean (The "Ice age" itself still had plenty of biomes, just far colder than usual, we've had a few mini ones over human history); and Mars is sort of a desert planet, Io (although still a moon) is highly volcanic....
There are Ice giants in the outer solar system already they are more like a perpetual bad ice storm than anything resembling Hoth.
