I think something along the lines of your "point 1" would be a suitable stand alone requirement for lifting the restriction; however I would suggest that rather than 5 hours flown with the instructor, you would have to say that at least 80% of the training hours flown by the student should be with the instructor looking to have the restriction lifted. It isn't always practical due to scheduling for the instructor to always fly with the same student (or vice versa) but it is expected that a student should fly with the same instructor on a fairly consistent basis.
