On Earth (in the real world) very large creatures tend to be on the somewhat ponderous and generally slow moving side. Elephants and whales come immediately to mind. Massive real world dinosaurs likely weren't all that fleet-of-foot. It leads one to wonder if a primate the size of King Kong could even support its own weight and walk. With that in mind creatures several stories tall really requires a serious suspension of disbelief.
However, TOS might have a precedent in "The Galileo Seven." In that 7+ feet tall bipedal creatures menace the shuttlecraft crew and one even attempts to break into the shuttlecraft by trying to crack it open with a boulder. Perhaps someone in a suitable costume(s) could do something similar to "wreck" a miniature of the heavy lander. If they can create a Gorn or Excalibian then they should have been able to fashion some kind of rockzilla creature. And you don't have to actually wreck your precious miniature. You could perhaps fashion a sort of cardboard or plastic shell for a quick shot of the craft being crushed. Then you have a separate miniature that is really a pile of barely recognizable rubble.
