Many of these risks don't apply to the lunar variant. The lunar variant won't be launching people from earth and won't be returning to earth. No re-entry, no landing flip, etc.
As far as descent, it will do final touchdown with smaller engines higher up to avoid kicking up rocks. During landing, I think pretty much any one of the 6 raptor engines can be used to abort.
