Thanks all for the comments. Sadly after visiting the IO they told me it's not possible. Hence I will have to apply for a new type off visa from the UK since I need to travel to the UK before my current visa expires on 22nd December.
Yes, that was my case. I successfully obtained my spouse visa in December after having a 60 day extension to my non immigrant multi O, thanks to the advice on how his forum. I also have the work permit too. The Q above is not for me but is an enquiry for one of my friends. Impressed with your detective skills James💪
