How about "cheki chiowa (the Dark side)" A story of an Ewok gone bad
Cheki was just a cub when the rebellion and empire fought on endor
But he never forgot finding his clans bodies after the battle
used as shock troops and then abandoned by the rebels
It was some years later that Cheki arrived in the core worlds and hunted down the skywalker
there he easily fooled the doddering old man into training him as a Jedi
Luke never stood a chance as the ewok ignited his lightsaber actually against his "master" and disemboweled him
Follow the story of one Ewoks revenge as he hunts down and brutally slays those who let his people fight men with blasters
Marvel at the brutality as he slaughters entire villages
Laugh as cute animated cgi aliens are blasted apart with heavy weapons
Noooooo NO no more Star Wars holiday specials. Please God no.
Frankly there is plenty of room to make Star Wars movies without having anything to do with the original cast, the whole period of the movies covered almost 3 generations and there was a lot more going on than just what we saw happening to the main characters, and the struggle between the Republic and the Sith has been going on for millennia.
My only worry is that Disney does not stupefy the whole thing and turn it into a joke.
