I don't think Amtrak would compete with Brightline if they were 'stops only to discharge passengers' West Palm and south. Where they would compete is for track time and would probably get a priority behind Brightline, Tri-iRail, and FEC. I know CSX/Amtrak ran an inspection train down the FEC when this was being discussed in the early 2000's, as noted. Having the Meteor on this route would have made a lot of sense with a bigger Star handling the Orlando, Tampa traffic. When the East Coast Champion ran via the FEC it took 5hrs 30min for JAX to West Palm with stops in St. Augustine, Daytona, New Smyrna, Titusville, Melbourne, Vero, Ft. Pierce, Stuart. Today's Meteor takes 7hrs 50min running via Orlando.
