Why do you think CO will OPUP you and your friend when there are 3 people willing to pay CO some $$$ and Miles???

OPUPs usually occur when the flight is oversold and nobody is on the waitlist for UPing so then they need to move people from Coach to BF.

Dont know if they will give it to say a Plat on an ElCheapo or a Silver on a much more expensive fare 1st, but unless some more BF people are no-shows Id expect that the 2 of you will end up in the seats you purchased,Sorry

What you might do is let the GA know you would be willing to be Vols (dont do this if you really want to actually or need to fly tonight). Alot of times by offering to help them out by VDBing when it doesnt come thru (they dont need anyone) if BF is open they will UPOP those who were Vols as a Thanks

Could be they will need to use you and maybe can get you out on TP or with a connection and you end with a couple of nice vouchers for your next trip
