Shadowing AND Mentoring

For some years now we have used shadowing and mentoring as a platform to ensure that we don't lose any opf the expertise of the staff as staff retire. For next year we will re-vitalise this important part of staff relationship building so that we can open up the discussions about pedagogy a bit more.
I have asked that teachers find themselves a different review mentor to the person they worked with this year.
They will look to shadowing others' good practice. They will also discuss and share the dilemmas re the child that it is difficult to move thinking-wise or difficult to create a relationship with.
A team approach may also work to open up the talk. We want to be able to track student growth in personal, work habit and thinking development.
The projects are a part of this development - teachers will need to talk to each other to find some assistance with areas about which they know nothing. They will need to discuss where to seek support and information so the students can do the project work.
Anyone got any further ideas about this?
