You understand that the Gateway isn't in an orbit around the Moon,

Was not aware of that. I was under the impression it was in lunar orbit.

Orion has nowhere near the delta-V capability of the Apollo CSM.


True, but I don't see why it matters since the CSM had about twice as
much delta-v as required. Orion has about a third less than the
Apollo CSM, so it still has enough to do the missions that Apollo did.
And I'm not sure that getting into an L2 NRHO is that much 'cheaper'
when it comes to delta-v.
