Speaking as a Protestant High-Churchman, I represent many of my brethren when I say that we certainly want another 500 years of division between Rome & Canterbury, so long as Rome retains her distinctive theology. Let it be 1000 years, or until the blessed Lord returns. We believe our clergy are validly consecrated & ordained, so nothing bites at our conscience.
At any rate, the major points we agree on have been fleshed out by now - especially in the last 50 years. All that remains, unfortunately, is that upon which we do not concur. Catholic Christians (whether Roman, English, Greek, or Russian) who care about The Truth will always prefer honourable division to slavish ecumenism.
