Pony Star Wars Characters

Good Guys:
Anakin Solo: Luna - Luna is the character most associated with Celestia, who is the best candidate for Obiwan. As an added benefit, Luna's character is easily able to also fulfill the Darth Vader role, via Nightmare Moon.
Obiwan Kenobi: Celestia - As the teacher of the Main Character, as well as possessing a number of similar character traits, Celestia is clearly Obiwan. This even extends to her disappearance at the hands of Nightmare Moon, who will be portraying Darth Vader.
Princess Leia: Rarity - Not a very good fit, but there's really not a better option for Rarity.
Luke Skywalker: Twilight Sparkle - Main Character, on a quest to find out who she is, etc.
R2D2: Owlicious - Twilight's pet who only communicates via Hoots, just like R2 only communicates with Beeps, Whistles, etc.
C3PO: Spike - Twilight's companion who is able to speak. Spike is rather different from C3PO, but fills the role nicely, nonetheless.
Han Solo: Rainbow Dash - RD = Han Solo. Self Explanatory.
ChewBacca: AppleDash - RD's good friend who is not the same race as RD. Easy fit.
Lando Calrissian: Fluttershy - A pony who is from Cloudsdale, is one of the mane 6, and is not RD. No more need be said.
Biggs Darklighter: Pinkie Pie - A good friend of Luke's. Granted, this may be better filled by one of Twi's acquaintances from Canterlot, I see no reason not to include Pinkie instead, as those are one-off characters.
Mon Mothma: Mayor Mare - Sidecharacter that seems to fit well into here.
Admiral Akbar: ???
Porkins: ???
Wedge Antilles: ???
Yoda: Zecorah - A strange foreign pony (zebra) that talks in an odd manner, and is wise. Easy easy fit.

Villains:
Darth Vader: Nightmare Moon - Chosen due to associations with Celestia, and the fact that it is Luna's evil persona.
The Emperor: Prince Blueblood - asshole who has a royal title. Best fit for the character, imo.
Jabba: ???
Boba Fett: Derpy Hooves - Both started as very very minor characters who only came to prominence due to massive fan followings.
