If it is an amendment 3 licence you should just be able to refresh it with 4 exams for the IR. If not, 11 exams
In doing that you should be able to convert the JAA one to an EASA one in one swift stroke (of course, money will be involved).
The Qatari licence will only really give you the ability to self-certify for the 14 exams - but you would be very unwise to do that given the state of the question bank.
LASORS is not valid any more.
