May be; but why would an average pilot choose a more difficult option when there is a more easy one? Just because the aces can do it why not teach & recommend the easy way to all and sundry and then the aces can choose to play from the rough instead of the fairway if they want. Extending flaps in the turn, SE, is likely to apply only to the base turn, or perhaps to finals if a long way out. It will be a choice to delay configuring. It will also be a choice to configure early on that once in lifetime scenario so you can be relaxed and stress free about it; and your mate. Delaying and risk being rushed, and possibly increasing the workload for both of you, unnecessarily, just doesn't seem the best move. Why would you. KISS seems appropriate.
We are not discussing if you can or can't, it's more of is it the best decision when 'called upon to perform' in that single moment in your career.
