I actually remember reading it and enjoying it, but it's non-canon now.

I liked Shadows of the Empire, but personally I don't think it should be a movie, just like I don't think Rogue One should've been a movie, or that any of these announced spin-offs and side-quels should be movies. The movies should be saved for the episodic films, which contain the stories with the highest stakes and most epic plots. The rest of these stories should be kept off the big screen. Star Wars should be an event, not something we see every year like Marvel and DC. Marvel and DC can do it because they need to show heroes in their individual stories before we have an Avengers and Justice League film, which are events themselves. But I don't think Star Wars needs to go down that same route. Star Wars is a different breed of summer movie, one that should not blend with another, otherwise, before you know it, every movie and every movie series will start to feel the same, and over-saturated.
Stories like Rogue One, Shadows of the Empire, etc, should remain off the big screen, as they had been before. In this new canon, they can be re-integrated into TV shows or video games, or comics. Season 3 of Rebels featured the Outrider - Dash Rendar's Ship - but sadly, not Dash himself. During this show, they could and should also incorporate Dash, Kyle Katarn (the original protagonist of the Rogue One storyline, and the original "traitor" in Force Awakens), Galen Marek, Mara Jade, and other characters and storylines that were active around the time this show takes place.
I also think that Rogue One (or Dark Forces to those who played the game that partly inspired the movie) should've been an arc in Rebels, and this arc could explain the absence of the show's protagonists from the movies by potentially killing them off, not unlike what Rogue One did. I've posted this in other threads, I suggested plausible ways to reintroduce characters and stories from the now Legends canon into the more aspiring condensed and organized canon without the need to sacrifice characters for the sake of tokenism.

He was rapey? Yikes, I don't remember that

A lot of people(such as me) are most familiar with SOTE through the N64 game, so to take him out would be like taking out the most identifiable aspect of the story. I think if you're going to take out any of the original characters you might as well not call the movie SOTE and instead tell a different story for that time period.

How is it a flaw that the Prince Xizor character is seductive and rapey?
I agree that Dash Rendar needs to be exchanged for Lando, though.

It would also be able to undo the flaws of the original story
Dash render needs to beep off and is replaced by a emotional arc of lando
Make prince baddie a better villian and less rape themed
Reshape the story for higher quality

I agree, perhaps a television mini-series too, or otherwise an anime theatrical.

A Star Wars two-dimensional animated film with the attention to detail and budget of, say,
Akira
would be phenomenal.
It is a tale told by an idiot, full of sound and fury, signifying nothing

No thanks. A high-quality two-dimensional animated film with highly convincing voice actors is the only way to go.

Lunas and his crew said it was Dash

Dash rendar ship is in a new hope so he is canon
The ship seen isn't necessarily Dash's. We can't assume that Corellian spacecrafts are all unique in model.

Yeah I feel it is something they will do somewhere down the road. Most likely after they finished the sequel trilogy. There are so many stories in the Star Wars universe. Another great direction would be even to go back to the stories that predate even the prequel trilogy. I would love to see them make Shadows of the Empire the most. Back in the 1990s when I was a kid I played the N64 game and had the action figures. So if the technology ever progresses to the state where they could make such a film that would be awesome.

As much as I'd love Shadows of the Empire to be incorporated into Disney's canon, it may be a few more years before they're able to properly replicate an 80's era Carrie Fisher and Mark Hamill, among other supporting characters, into the many action scenes they would have in Shadows. We're almost there though.
