So, I know this'll likely be shot down, but I wanted to pose a potential suggestion regarding maximum ship sizes for Super Star Destroyer-style vessels. I think the maximum length should be raised to 18k meters, BUT with certain restrictions. Major factions'll be limited to a hard maximum of up to three Super Star Destroyer-sized vessels based on the amount of hexes they presently control, to act as command ships.
Super Star Destroyers were always meant to be special set pieces, so why not give them this bigger upper limit? In terms of writing and balance it won't really affect things much. Writers'll always find a clever way to take them down, and such a hard limit seems silly when they're big targets anyway and they're meant to simply serve as yet another tool for potential plots/storylines.
A potential beneficial side effect of this would be that present "SSD"s could be reclassified as Star Dreadnaughts and made a little more available than they are presently.
