Stability problems can happen at any height, so the only things special about the approach in terms of not flying a full flap sideslip, are (a) it's the only place you'e likely to, and (b) you have much less height to deal with any resultant loss of control.
Also, if you've not practiced something already, during a genuine emergency isn't really the time or place to experiment!
My advice if you're over-high is either to pick a different field, or to perform an S-turn or two whilst keeping your landing field in sight. (Or turn base later, which would be my general preference, but that to some extent depends upon how you fly your PFLs.)
