ICN - PEK -TAO - LHR

Would this be possible? I already have a one way booking from Seoul to Beijing. I would then like to book a flight out of Beijing 6 days (144hrs) later with final destination London, but it will have a short 3hr stop in Qingdao. This PEK - TAO - LHR flight will be with one and the same airline on one itinerary/booking.
