Fine, you want a better analogy?
HMS Abercrombie. Monitor of WW2, carried a single twin 15" gun turret forward, was a light cruiser in nearly every other respect. (And I mean a European or Japanese light cruiser, not one of the monsters like the Brooklyn the US turned out since they designated cruisers on gun size and not ship size.) Abercrombie never engaged an enemy ship larger than an MTB, but she was one of a number of prewar design studies conducted by many nations in the concept of a cruiser packing battleship guns, and much thought was given to the proper employment of such a ship.
The general consensus was that employing such a vessel against a genuine capital ship not previously badly damaged would be tantamount to suicide, but she would be a valuable asset in a cruiser vs. cruiser battle or for bombardments, bringing the weapons of a battleship in a lighter, faster package. The problem was that such a ship would be difficult to provide protection similar to her cruiser brethern (only the Germans managed it with their panzerschiffes, but they made the only truly serious attempt), and being armed like a battleship, somebody somewhere was going to be tempted to use it like one.
Sounds like a Lilth, yes?
Granted Abercrombie was slightly underarmored for a ship of her size, but as we're dealing with FS where weapons hit a lot more often then they did in the 1940s, and Abercrombie was significantly more sprightly then a true battleship (she handled like a light cruiser, because that's essentially what she was), the parallel is actually quite workable. The Lilth isn't speedy and sprightly but lightly armored because that wouldn't help it much. Instead it's heavily armored but slower than its apparent ability to generate power suggests it should be.
