As an FO I often fly with Captains who are in the process of preparing for sim details and/or completing the recurrent tech quiz. I've had "so, what do you personally think we should do if we come around base turn, select flap 1 and got a Master Caution with flaps stuck?" ... in less than ideal weather with some other issues to consider. Encouraged a 4 minute debate at the end of cruise to include things such as landing performance and other items. Turns out we agreed on the outcome, but it was just normal chit chat, not an assault on the limitations of our knowledge. End result is both of us feeling good about ourselves through reaching some agreed conclusion and confident in our ability to deal with such a situation. Can't see a downside, unless the other guy is obviously not in the mood (something you should be able to gauge).
