What would you whif a YAMATO class battleship into if you could?

[Diamondback]

Belated spitball: what if, as part of Japan becoming a US quasi-protectorate under the terms of the MacArthur Constitution, they were still allowed to build large warships but ONLY to operate in joint task-forces with US Pacific Fleet, say specifically restricted to operations patrolling Japanese or American waters in partnership with USN ships? And as part of this what-if, the unfinished Hull 111 had never been scrapped (admittedly in OTL this was done to provide materiel for the Ise/Hyuga BBCV conversion) but was refitted as "Yamato 2.0" including the Shinano and planned Hull 797 improvements and over the decades given the same upgrades under US auspices as the Iowas? And further, what if Hull 797 was proceeded with postwar, again under US auspices and operational control, as a second Shinano but given the Midway Refit treatment?

This page about the genesis of the Yamato has some interesting stuff:

This is the all main turrets fwd. configuration closest to Yamato, as built.

Battleship guns forward and the firepower of a cruiser aft! What's not to like?

You mean like a supersized, Japanized HMS Rodney?
