It would depend on a) how many seats up the front are left up the front once they've cleared the waitlist of pax who have requested upgrades on points & b) if there is an oversale still in the whY cabin once the points upgrades have been done the day prior.
Getting 4 op-ups would be harder as if they do an op-up for your friends QP Bronze friends that could come at the expense of other WP or SG pax travelling. You'd possibly have a better chance if it was just you & your partner linked as a couple.
