Can we not just base the English teams on the nine official regions of England?
That being the North East, North West, Yorkshire and the Humber, East Midlands, West Midlands, East of England, London, South East and South West. Nine regions seems like a reasonable division to get a decent number of teams for the tournament, and if that's the case I'll apply.
