The AoC shouldn't be both the administrative and pastoral leader of the C of E. There should be some decentralisation of leadership if the Anglican Communion is going to stay together.
A lot of people in this country, let alone the rest of the world, don't accept women priests or bishops, let alone a female AoC. Add in the issue of homosexuality and it's hard to believe there's anyone that could be a unifying figure for all.
It's a bit ridiculous that in 2025 the Anglican Church is still run from Canterbury. As far as I'm aware (lifelong and practising Anglican) there isn't a process to go outside the UK bishops for the AoC appointment. I know African bishops like Sentamu come to the UK, but that's not really a great way to work it.
They should set up an administrative HQ that deals with appointments of clergy, salaries & pensions, manages the historic buildings etc. Then have regional leaders who meet together and decide on a head from among them, maybe for a fixed term, to lead on doctrine and other issues.
