For FJ jocks to stand around in at air shows looking steely-eyed perhaps? Not that I can believe they'd ever wish to do that, nor need a leather jacket to achieve the effect.

Au Contraire, I have seen plenty of 101, 10 and 216 aircrew wearing these (in fact some had brevet badges made up in Sqn colours). Also there is more than a fair share on some of the ISTAR types.
But back to the question. Do you think we should ask to wear them with No2 Blues. I've seen plenty doing it (including the old CINC and a couple of 1 stars). Simple answer of "yes", "no" or "maybe" will suffice and don't forget to think whether you might want to in future when the dreaded ground tour comes along!
