The Soviet Lunokhad lunar rovers from the 1970s were in the same weight class as curiosity, and they landed and deployed successfully on top of a traditional soft lander with legs and folding disembarking ramp. This suggests at least the final stages of landing with a rover this size could be accomplished on a large traditional style cushioned solid lander.
In any case, were there ever to be a manned landing on mars, it seems that such a landing must be accomplished using a even larger traditional lander with cushioned legs.
