I'd try it. I presume after removing the top floor or two the void space fills up, so no where to collapse to.
I've seen contractors put skidders and mini exs up high, but never any full size beasts like that.
I wouldn't put ME up there, much less in an excavator.
I'd do it, for a price ($$$,$$$,$$). Lol
My favorites are the ones that go on top of huge concrete cooling towers.
