This is silly. The maximum Gee load permitted with the flaps down is +3.0 Gee. At 60 deg of bank you are already at 2.0 so a hard pull to try to get a stall is likely to get close to the max load.
There is no reason to do this and the POH is clear that spins are prohibited with the flaps down. If you did get it to stall with 60 deg of bank and lots of power you are going to be in for an interesting ride.
In any case the whole point of the landing configuration stall is to show the student that the airplane will be in only a slightly nose up pitch attitude when it stalls, unlike the introductory stalls where the aircraft will be in quite a nose high attitude. Therefore it is a good demonstration of the importance of maintaining the correct pitch attitude to maintain airspeed on final.
I always teach this exercise as if when on final, finding yourself low you raise the nose to try to get to the end of the runway instead of adding power.
