A couple of points there which might be pushing the certification tick in the box.
Possibly be a good idea to have the studes read through the relevant bits of FAR 23 and AC 23-8 (versions appropriate to the particular training Type - ref TCDS) to get some background prior to frightening themselves.
There isn't, necessarily, a danger in doing something different to the certification .. just a potential concern that something surprising might turn up along the way and then the pilot is on his/her Mat Malone. If the bit which is surprising has some underlying problems for recovery, that just might be beyond the non-FT knowledgeable trainee pilot ?
