I don't know much about the Titan II but some of those early rockets couldn't support their own weight and relied on internal pressure to maintain structural integrity. If they lost pressure they'd crumple. We already know the Superheavy booster is more robust than that so maybe with just some internal cooling it can survive hot staging.
