One thing I've have to have to make this project stand out is a good lunar surface.  My current plan is to wet the landing surface with water, sprinkle on some grout, let it set for 30 minutes,  remove any excess, then repeat until it looks reasonable. I think this may work....

A slight mod to the suface testing. Now spray the surface with adhesive, sprinkle on some grout, spray again, repeat. Also trying to insert a few random rocks into the mix. I think this is better and getting very close to the effect I'm looking for.
