I don’t think so actually. I occasionally had two conflicting bookings (not with QR but other carriers) mostly stemming from the fact that some ticket was non refundable and I just booked something else.
Even if there was such mechanism OP could have booked a TK flight instead. I am not sure if a transit on two tickets is allowed via DOH currently, but if it is they would have admitted him onto the flight. He could have then cancelled the TK flight and flown the initial itinerary. Presumably he would then have violated some Qatari immigration law and might have been flagged upon boarding his return. So presumably not the best idea.
Even easier would been to book LON-DOH-FRA and he would have been fine. Funny how inconsistent rules are...
