Not entirely certain on that; a stretched Burke (i.e., a Flight III Burke) wouldn't really provide any more capability against Abyssals than the existing ones, and the CA's armored hull would hold up better against them than a Burke that's only hardened against .50-caliber fire, and even then only in the vitals.
Assuming they guide at all on the Abyssals. The one advantage a gun would have over an AShM is that it's unguided, so a modern 8"/55 like the Mark 71 Major Caliber Lightweight Gun would presumably be as effective as a heavy cruiser's 8" guns were in WW2, since it's literally the same gun in a newer, lightweight mount. (The problem being that you'd need to put a hell of a lot of them on the ship to get a big enough broadside for effective fire.) After the MCLWG's original platform, the Strike Cruiser of the 1970s, was cancelled by Gerry Ford, the Spruance class DDs were built with structural foundations and strengthening members meant to allow them to be retrofitted with it replacing the forward 5" gun, though the upgrade was never carried out. At least as recently as 1991, there was a design study done that showed it could also be grafted onto the DDG-51 Flight I, replacing the Burkes' 5" gun, albeit with a number of significant drawbacks.
And technically, we have just recently built three new gun-fighting ships, in the form of the Zumwalts. They have no real AShM capability, and only self-defensive SAM capability; their primary weapons system is the 155mm Advanced Gun System mounts. Granted, those are mainly meant for shore bombardment use, but they do remain an example of a modern gun destroyer.
My guess is that there's a good chance that war-production Burkes will be equipped with either MCLWG or AGS mounts in place of their 5" guns (and possibly one of their VLS mountings, in a configuration designed to allow it to be swapped out again for the VLS cells in the future), simply to provide them with a bit more punch against the Abyssals, particularly since the US Navy has no super-heavy AShMs or any way to graft them onto our warships even if we buy them from the Russians (who would almost certainly be hoarding production for themselves, given how they'd doubtless be going through them like toilet paper). It's not ideal, but at least it'd mean they could hit with something that could actually damage a cruiser instead of just a five-incher--remember, cruisers were specifically designed to be protected against destroyer guns, meaning that they were armored against five-inch fire...
Hopefully, in universe, there would already be people gearing up for big gun construction. Either private companies who want to have a weapon system for government contract, or the government itself, since apparently gunfire is what consistently sinks abyssals. Guided missiles apparently have all the accuracy of rocket volleys or trying to bomb ships with heavy bombers. I would think the government would concentrate on cruisers and destroyers, gun heavy armament except for ddgs that seem to be good for AA work, light on electronics that get messed up by abyssal influences. After there are no more abyssals these ships would become razorblades, unless a couple are kept as memorials to the war. Not good long term investments, but neither were a lot of the ships, equipment, and aircraft built for WWII. Wars are always costly, and the debts last for generations. And that is just the financial part.
