Funny you should mention that, as there's a real life example: Initialy Mogami class cruisers were equipped with 6" guns and classified as CL. After japanese upgraded them with 8" guns they were reclassified as CA.

Another example: US Cleveland class CLs were larger in size and displacement then, say Aoba class CAs. So size matters, you say?
