You mistook my point. Not that New Shepherd can be used "as is", but merely that Blue Origin and SpaceX have developed propulsion-based landing technology and NASA/Boeing have not. There's a much shorter development path from New Shepherd/Dragon 2-->LEM, than from Orion. And of course SLS could launch a LEM. The problem there is that it costs $2 billion/launch. That's "just a bit" of a price premium relative to Falcon Heavy, or whatever the fully reusable generation of rockets is going to cost.
