Only a couple changes in your skill tree: I swapped Discipline and Lore.
I left out Cassandra's Tears because Divination is the kind of thing that would fall under The Force (Soulfire) or Guide My Hand if it is to help someone or further the agenda of the Light Side.
Superb: conviction, weapons, lore
Great:discipline , athletics, investigation
Good: endurance, scholarship, alertness
Fair: rapport, contacts, empathy
Average: pressence, might, craftsmanship
-5 Sponsored Magic: Soul Fire (Light Side of The Force
-3 Refinement
-2 Righteousness
-1 Guide My hand
-1 Holy touch (probably unnecessary with Soulfire)
-1 The Sight
Sunts
-5 in random stunts.
18/20 refresh
Foci: X 10. I haven't built a caster in ages so my numbers are probably all off. I'm sure someone will correct my calculations. In any case, this is just an example. Essentially, you are making a crafter with Soulfire. Since Jedi craft their own sabres with crystals and use crystals to attune to the force, I used that as the fluff for your items.
(Adegan: Pontite)Crystal necklace: +2 Soulfire (Light-side Force) control (2 slots)
(Kasha) Crystal ring:(2 slots) +2 Soulfire (Light-Side Force)Power
Lightsabre Crafting tools(4 slots): +2 Frequency; +2 Power
Enchanted Items X4: (2 slots)
Light Sabre:
Weapon 7 attack: X3 uses
Athletics: 7 X3 uses (fluff is that you cut through a wall or door and pass through). It could be a Might skill check or Burglary too...depending on what kind of utility you want.
Deflect Attack(Power 7 Block): X3
Mephite Crystal: Power 7 Potion slot, usable X3 times
Essentially, you are a Crafter/spellcaster with The Light-side of the Force as your Sponsored Magic (soul-fire because it costs 5 instead of 4 refresh so it should give you the ability to down-grade toughness, which makes sense since lightsabres cut through everything).
Spell casting: Accuracy 6(or 7 with righteousness); Power 7
Your Rotes could use the typical tropes:
Levitate (athletics skill replacement)
Attack: use the force to telekinetically throw things - although, that might be under the purview of the Dark side (same as force lightning)
Block: to deflect attacks and protect allies
Jedi Mind Trick: Influence people by creating powerful maneuvers like: 'these are not the droids you're looking for'
Veil: creates a sound that distracts people and makes them look the other way so you can shut down the death star's shields
TL; DR
Jedi are essentially space wizards.
