I think it's more likely that Pres. Trump will just defer to Elon Musk on anything having to do with space policy. This means anything that survives from the Artemis program will be bent to Musk's oversight and reflect his personal priorities. I gather Musk wants access to U.S. tax dollars to fund his business enterprise, which he currently has under contracts administered by NASA that reflect NASA's goals. I gather he wants to remove policy and oversight from that equation and just have the dollars to fund SpaceX.
Musk via DOGE will effectively control NASA. Musk has said he doesn't want to go to the Moon. Therefore it's possible Artemis will be redirected toward a Mars-first goal. As long as Musk continues to make Trump look good, Trump will go for it.
This is all conflated with the problems with Boeing, which has truly lost its way.
