Modular refactoring possible?

You can use the views using a good old fashion include
As for the models, they have dependencies within the CI stack such as the base Model, the database and active record classes etc, so if you plan on using models like they would be used within CI, but outside of CI, you could need to stub part of this, or manually load the dependencies.

I would personally recommend starting from the controllers, creating functios for each page, and then calling the code you execute in the current systen... you can then move from there
