If you want to change jobs, need a degree and have financial resources to do that, just apply to a decent 1 or 2 year Master program. That's practically 100% guarantee that in 1 or 2 years you will be more employable than now with a higher degree you have now.
The probability you get CFA charter in 2 years is much lower. Besides, I think, CFA only makes sense if your company pays for the program and the annual member fee.
