Ability to change page content type via admin

Is your proposal related to a problem?

Whenever changes to a projects requirements are made where it becomes necessary to partition a page or group of pages into a new page model. Currently this can only be achieved, as far as I know, my modifying the database directly which is not ideal especially if a large number of pages need to be changed.

Describe the solution you'd like

Ideally, a drop down list of available page types against each page where alternative page models can be selected.

Working on this

If someone wants to take this further, I think it has to be one of our established contributors / maintainers to figure out what the backend implementation looks like.
