To be fair, in this hypothetical, if SHA-256 had indeed been broken, the difficulty wouldn't matter because the underlying cryptography keeping Bitcoin secure would itself be vulnerable.

However this won't happen out of nowhere from quantum computers. When a hash function is close to breaking there will be research leading up to the final crack.

There will be plenty of time to transition to a more secure alternative. Satoshi himself discussed this.

I have faith in bitcoin devs to address this threat should it ever materialize. And as time goes by with hyperbitcoinization unfolding, the number of bitcoin devs will only increase and the amount of support to protect bitcoin will only increases. The greater the adoption the greater number of people with incentives to protect bitcoin.

Yup they're certainly more than able.

I just hope it doesn't become another drama. Hopefully not because the need for keeping the Bitcoin network secure is of course paramount.

Lamport signatures fix this.
