Warp,
Being a pilot with a major carrier really isn't a part time job. Were you to be able to move into an office based role - to begin with probably as a grunt in your fleet's training office - you'd still be expected to fulfil your role as a pilot to the high standards expected of you. To get a job as a trainer you'll have to show exceptional skills anyway. Any job/role in parallel is likely to be flying oriented as you'll likely have no relevant skills in any other branch of the business.
Would you not be better served - with a quality degree - in applying for the office job straight away. Getting onto the FPP and then completing the training is a major step on it's own. You really have to want it so much that you can taste it. Considering another path so early, and I question your motivation
