The other possible exception to the inclusion of Rebel / New Republic Star-Dreadnought / Battlescruiser sized ships is that it can be argued that you don't really need them if you're not out to keep the peace in the spacelanes through superior firepower. Once the Imperial Remnant was dealt with (and taking the traditional science fiction early 20th century naval analogy pretty closely) you don't really need battleships to keep the peace: you need ...well..cruisers. Which is what it looks like the NR built.
But some up and coming conqueror always seems to appear and, sure enough, you would figure that the NR would ultimatly decide to build at least a modest battlefleet to deal with the really big stuff.
Personally, I've always been opposed to the NR building star-BC/DN's because I think that their civilian leadership would never allow it. Frankly, I'm shocked that they got permission to build their new Star-Destroyers, let alone anything larger...
I'd imagine that the construction by the central authority of anything large enough to destroy a sector defense fleet all by itself would be...frowned upon by the post-Imperial electorate.
And I don't really see anyone in the SW universe building the equivalent of "star-monitors" (in this case, battleship scale warships without long range hyperdrive capabilities)...Wait a minute! Yes we do! And they did! The ICS books make it pretty clear that the Mandators and Procurators were originally built without the endurance or hyperdrive capability to practically make long range jumps!
We could go with a similar concept! The Mandator and Procurator go up to Mark 2 in the canon, assume that KDY built Mk3 variants for the NR which returned to pre-Clone Wars sector defense mission! Upgrade the technology to keep pace with Imperial era "fads" (i.e. add a grav well generator) and you've got an NR star BC and star DN...but without the ominous "I'm going to take over the galaxy" overtones. You'd want to strip the assault transport complement down quite abit ... but that would logically allow you to really up the fighter load. The best part though appears to be that
Eville Jedi has a Mandator model!!
