If you mean physrep just like it was in the movies then, yep, you can only do the hairstyles, costumes and the wildwestesque attitudes 8)
If you wanted mechanics to simulate SW items then how about:
Light Sabre
Just use a toy light sabre. Maybe you can’t simulate parrying blaster shots, but you can simulate everything else (i.e. everything it touches is burnt and cauterised, but they bounce off each other). If you had lasertag firearms then a Jedi carrying a lightsabre could take minimal/zero damage from blasters via a switch on their gear, up to a certain rate of incoming fire (just like in the movies - when surrounded, the Jedi’s either run or give up).
Blaster
Some kind of laser tag gun or Airsoft pistol perhaps.
Jedi Powers
Something like Push or Pull would operate similar to the Mordavian vampiric Fear, and the Mind Trick would be similar to Faerie Dust. You would have rules about proximity (i.e. 1-2 metres etc) but no other props would be needed.
Like Faerie Dust and Fear, the players are expected to keep track of their usage, and are not allowed to exceed their daily maximum etc.
Consider disallowing Lightning as this is only something the extreme master dark Jedi every did (not even Darth Maul could do it).
Jedi Speed would be handled by HandsOnHeads as the Jedi runs to where they are going (distance limited, increased as they improve levels).
Space Craft
Use a couple of rooms, and have a LAN set up that can simulate the space combat.
Probably the main issue with Star Wars as a larp genre is the propensity for characters to bugger off all around the galaxy in true space opera fashion. Unless the game is entirely mission based, you’ll need to find excuses why the PCs don’t rock off to Tatooine to go pod racing etc.
