One of the many problems with SLS has been that there were no missions defined for it. One of its contractors, Boeing, has accordingly decided to define some lunar exploration architectures that utilize it. Of course, they don’t have any comparisons with the much cheaper alternatives that don’t. If I were SpaceX (or ULA, though for political reasons they probably can’t), I’d be putting some together.
