It seems to me that you need to decide which career path will hold precedence over the other.
I've always followed my ag. science path, and the flying became the 'hobby' if you like. It's worked well for me, as a travelling consultant - the flying became the means to travel. Nowdays I instruct a little more often as I've retired from most science jobs. And, I'll stay with it until the med1 expires. After 48 years and near 12k hours in my 2nd profession - I can definitely say this way... works.
Several others fellow scientists in Oz have also been able to steadily improve their flying quals - without losing anything in career path #1. The others I know of are all now ATPL/CIR, or CFI/Gr1 and still enjoying their flying.
I'd be surprised if there aren't many more economists, commerce,business,engineers, pharmacists out in GA/RAA land -enjoying their 2nd career, and filling a part time niche.
happy days,
