I don't have any specific requests, I just want more new ships in these movies.
I don't count the new X-wings, Tie Fighters, or even the gorilla walkers as truly "new" vehicles, just upgraded versions of old ones.
Looking at it this way, there really haven't been a whole lot of new vehicles in these new movies at all, which is one thing that really disappoints me.
There was the U-wing, the Tie Striker, and the tank in Rogue One.
There was the Quadjumper and Han's new freighter in TFA.
There were the Canto Bight speeders in TLJ, and DJ's ship (which has admittedly grown on me). It's debatable whether the Ski-Speeders count as new vehicles or a thinly veiled rework of the B-wings. Even though it resembles a Star Destroyer, I'd argue that the Dreadnaught somewhat counts as a new ship, since it's function is entirely different.
I'm probably missing a couple, but there has been a severe lack of new, inventive vehicles in these new movies. In my opinion the only one with truly interesting new vehicles has been Rogue One.
