This is a question posed for competition play, I know that either Luke is interchangeable on the table as long as you are clear with your opponent which luke you are playing with (which should also be clear from your sheets)
I also know that hobbying your figure is also legal, my question is that are you allowed to bring a rebel comms specialist along as a rebel trooper, also the "Gideon" rebel leader could you play them as a standard rebel trooper leader as as long as you are clear that the unit is still just the standard rebel trooper unit. (In much the same way the newer rebel trooper expansion can have the figure as a standard or enhanced leader)
If the above is legal can you extend that to actually replacing the rebel trooper unit with, for example, the rebel commando figures and replace the sniper figure as the dlt20a , and perhaps having a pathfinder unit as another rebel trooper unit. This helps with visual variety of the rebel trooper units (esp if you don't bring along commandos pathfinders) while also providing thematic cohesion (example using pathfinder units as rebel troopers in a Scarif themed army).
Just curious as to how far you can take it before it's competition illegal.
