Thanks for all your replies and comments.
Basically the idea behind my question was that I wanted to create a difficult approach for the student to perform without having to tell him what to do.
We are lucky enough to have a VOR nearby our airport which we can use for initial training. (Yes I expect the usual comments about procedures like this) Currently I tippex out the stated altitudes and replace them with the relevant altitudes. Before anyone mentions trees! This is not done lightly, I have Jeppview and several maps and calculate accurate descents, plus having the benefit of a g1000 cockpit we have the terrain feature. It is always done in VFR.
All I wanted to do was create more complex approaches featuring all different types of techniques in order to test the student.
Like i said, thanks for the comments.
