What it would take to turn Tiger into a heavy cruiser

What changes would a Tiger-class cruiser need to become a properly structured and armored heavy cruiser?

Its armament and belt were plausible, but the finished ship would probably need to displace about 13,000 to 14,000 tons standard.

The proposed heavy-cruiser Tiger begins with a four-inch belt and ten 8-inch guns, which are credible features for the type. The difficulty is providing a proper hull structure and acceptable protection without pretending the ship can remain treaty-sized. The existing figures already run well above the nominal 10,000-ton standard. A realistic design would likely exploit concealment or tolerance and settle around 13,000 to 14,000 tons standard.
