The big Mon Calamari cruisers, the closest thing we see them field to ships the size of Star Destroyers, and plainly the backbone of the fleet they deploy in Jedi, seem (though our evidence is limited) to have a lot more space dedicated to hangar bays than the Destroyers do, and not to have the kind of firepower needed to stand up to Star Destroyers in a straight fight—I think casting them as something akin to gun-armed fleet carriers of WWII, like the Royal Navy’s Illustrious Class, isn’t too wild an idea.

[edit] though, I do think that line of argument’s a bit weak. I could see going either way on the question of whether the Mon Cals slot better into the “fast carrier” paradigm or are better regarded as filling the role of heavy cruisers or battlecruisers. Not a lot of Star Wars ship designs slot quite so clearly into a fast carrier designation as the Republic’s primary Clone Wars warships.
