Landing Flash Gordon style with exposed ascent engines on an unprepared dirt and rock surface is not a recipe for success regardless of the gravity involved. Until they come up with some Marston matting style deployable landing surface, their system will never work. Furthermore, Apollo 15 was tilted 10° with a relatively squat design to the LEM. A skinny tower would not have survived that.

It's supposed to handle up to 8 degrees but there's lots of locations at the south pole with < 2 degrees of slope.
