I hated the last 3, and if he makes another 3 I can't see how they could possibly be better.
It would be cool if in the spin-off a huge civil war over slave trading breaks out, all of Han's friends die, and he becomes a bounty hunter who turns in the same guy for bounty again and again and then frees him and takes him elsewhere. Meanwhile the antagonist Boba Fett (escaped from the Sarlacc) finds out about a soldier in the civil war who hid a great fortune on a tatooine grave yard- but it turns out that only Han knows the grave, and his dumb criminal partner knows the graveyard.
It could be 3 hours long with a great soundtrack and camera work and very little dialogue.
Or maybe that could be the 3rd of the new trilogy- with the 1st being about Han Solo protecting a village of ewoks from bandits, and the second about Han Solo and long lost enemy that looks a lot like Boba Fett, but is more of just an old man who's sister was raped and killed, hunt down bandits.
And then Harrison Ford could direct another movie that hints that he might be Han Solo to help advertise the movie, but he is really an angel of wrath.
Oooh, and they can make a spin-off with Mark Hammil where he and 7 disciples protect a village from bandits, and 4 of them are killed, and the village reaps all the profits and shun the 3 remaining jedi who realize they are fucked.
