What a 24 hour Falcon 9 reflight would look like

Iron Man's next objective was to refly a Falcon 9 in 24 hours. We can infer the 1st 24 hour reflight wouldn't be with a customer payload, but some kind of demo mission. They would have to

transport it from LZ-1 to the hangar with the landing legs intact
stack a new 2nd stage, new payload fairing, & payload
transport it to LC-39


Static firing the engines would have to be skipped. All the data which is analyzed manually would have to be automatically analyzed. It was a horrible waste to refurbish an old shuttle carrier, but still have to detach the landing legs. These can all be overcome with more construction.

The mane problem is the sensors. Sensors dogged the shuttle program for its entire life. Today's sensor glitch was an instant 24 hour delay.
