Ok, so there a plethora of beloved ships that have never gotten movie treatment. But even as the series moves on with Ep. 8-9 and the Rogue One style one off movies there are opportunities to include them. For instance, the TIE Defender, Avenger, E-Wing, etc. all represent late GCW/Early republic era ships that could easily introduced in Ep.8 as both sides getting desperate enough to break out "museum pieces" that were cutting edge in their day and still able to hold their own against the more modern fighters. It would also be an interesting wrinkle if they threw in "Imperial Remnant" factions that opposed the First Order. Whether for ideological reasons or more practical ones (like they don't think a war with the Republic can be currently won even after the First Orders strike) seeing these Imperial ships fighting along the Resistance could make for some interesting subtleties.
The Han Solo movie would be an excellent place to introduce the Decimator into cannon as it was designed to be the "evil Millennium Falcon". It could also be a good place to introduce the star ship of some of the other big name bounty hunters/scum pilots as Han runs into them. I just hope they don't try and make Han seem like a good person before he joins the Rebellion. Cause he wasn't supposed to be. He was a smuggler for a major criminal cartel. Let him be a protagonist and don't try and make him a hero in that movie.
If true the Obi Wan movie likely won't give many opportunities for ship conflicts since he spent to majority of that time between Ep 3 and 4 hiding and protecting Luke from discovery.
A Rogue Squadron series would be an excellent way to also introduce and focus on the ships and pilots on both sides of the GCW.
I also would watch a stupid number of times, a movie that was more a collection of short stories showing us a bit of backstory on each of the bounty hunters Lord Vader called upon in "The Empire Strikes Back". While I would also watch a full on each, a movie doing a sort of highlights reel of Bossk, 4-LOM, Zuckuss, IG-88 and Dengar would not only give us on screen representations of their ships but give greater context as to why THESE were the guys Vader called upon to hunt down Han Solo.
