Dawg,
You don't say much about your personal circumstances except for how much money there is in the bank. However, bear in mind that whatever route you take, you're unlikely to get a job at the end of it - but that the situation is improving.
Therefore, I'd suggest that you work towards your ATPL part time, and continue in your current career. That way, you'll still have a job which will pay the bills once you've finished your training. This is what I'm currently doing.
You don't say how much you currently earn, but if you're able to save that kind of money, I'd guess your current income will be sufficient for you to be able to keep current between finishing your training, and getting that first flying job, which is also important.
Good luck!
FFF
