I think your question was along these lines..."My wife makes lots of money, I don't work, it would be cool to get my ratings behind her back, then show up after flying my first trip and in my uniform and say, SURPRISE I'm a pilot." Accurate?
Reality:
Learning to fly is not something you can do quickly. 150 days is the bare minimum and you would need to study your ass off to get it done.
Learning to fly is not cheap, the 150 day program at ATP is around 60k, if you can spend that much without her noticing, buy your own plane and have fun.
Your first job won't be at a regional. You need to build hours to get there, you'll finish at ATP with 190 hours, You'll need much more than that to get to a regional. Most flight instruct, ATP might hire you if you meet their expectations while training, but you'll need to move to where they need you, not where you want to be. It could be the same location, but I don't think there are any guarantees regardless, you need to go to Florida for the training and to be placed.
When you do get hired at a regional, you wont fly day trips. You start at the bottom, flying crap trips when needed, where needed. You'll be gone 4-5 days at a time. Again, doesn't matter because you'll first need to interview then go though training, which is a month or more away from home before you ever get to fly a trip and call yourself an airline pilot.
I don't mean to be harsh, but you are not going to win many people over by coming into a forum filled with professionals and aspiring professionals asking how you can turn their profession into a notch on your belt to impress your wife and fill your days.
