Or more likely, re-scope the mission fly on multiple Falcon Heavy flights.
Fly Falcon Heavy multiple times and you're still cheaper than SLS.


NASA will run its token test flight on SLS around the moon and back.
Then, when it runs out of SSMEs and asks Congress to fund contruction of
more SSMEs, it will be told to use commercial launch services. (aka
Falcon Heavy or whatever).


Don't bet your lunch money on it. They've already spent billions to
set up a production line and option seven or so engines from it. All
that stuff is happening in someone's state. The argument will be made
that no commercial launcher can boost what SLS Block 2 can...
