Sorry, but if Qatar is looking for a "Lo in Hi-Lo mix with Rafale", then they would buy the Gripen ...
Defence sales are not only product specific they are politics specific
Same reason Qatar has bought and is buying more fast attack crafts from Turkey final number more than 20 units
Or UAE purchase of the Cirit missile from Roketsan the finally tally is estimated to be as high as 10,000 missiles of which 4,000 have been delivered this while GCC has access to the worlds top arms manufacturers
JF-17 success does not rely on a export market but the domestic Pakistani market, if PAF was desperate for a sale they would have joined the coalition in Yemen war but they refused and refused by a large majority also same is true for Syria
If PAF demonstrated JF-17 in Yemen for sure bags of orders would be following up, GCC country's would probably even buy the jet just as a repayment for Pakistans participation but that is not how Pakistan roles and it's not their baggage to get involved a very wise choice in my opinion
JF-17 has possibility in any Arab country, many Arab country's know the PAF score they have a healthy respect and remember all too well the record in Arab-Israeli wars, no brag just the way they role
If K-8 and Mushshak and Super Mushshak can do it so can the JF-17, although 2 foreign exports have been secured in my opinion already
