I think the issue with the current hoverslam solution is that the timing of the rocket relight is critical to the rocket hoverslamming (and not just regular slamming). I don't have the answer to this but imagine that if an engine fails to relight at the correct time there's a much smaller (or maybe non-existent?) margin of error. A plane on the other hand has two engines and can also generally just glide to the ground in the event that neither of them are working.
