Why isn't your resume good enough today? If you don't think it's competitive now I'm not sure getting a light civilian TPIC job is that much of an improvement.
I suggest making resumes for your current experience level and then making a new resume for 1, 2, 3, 4 and five years into the future. Make one for choosing Option A or Option B. Decide at what point you think you're resume is competitive or highly competitive. Compare the future Option A or Option B resume at that point.
I've working with a retiring squadron commander. Several type ratings, IP, Stan/Eval, etc. Loaded resume. He could get a civilian TPIC job and do fine. But even he's looking at filling the 121 squares, if he doesn't get hired before he separates, by getting a regional FO job.
