Hey mate,
I have worked at two different airlines where there have been pilots who are also qualified doctors. One of them was infact the airlines medical examiner as well. He had three days a month where he ran crew medical exams in a little rented office at the airport. He was always in high demand and you had to book about 6 weeks ahead. Not only did it make use of his medical training but it also added a nice little supplement to his income. He used to say that doing aviation medicals for existing crew was easy money, the exam generally only took 20 minutes, the majority of guys and girls that come to you are in good health and the pay is great.
So go for it, finish your medical training, get qualified and then pursue the flying. At some point you can sit the Aviation Medical Examiners paper and you will be able to mix both qualifications.
Have fund.
