While some would argue that you have the "grass is greener" viewpoint, as a long time major airline pilot, I have met career change professional who have enjoyed the change. Obviously, you are intelligent enough to have run the numbers to understand the financial hit. But at 33, you have looked at it and realized that money isn't everything when you are still looking at 30+ years of work. The 7 off/7 on schedule gives you tremendous flexibility. I don't want you waking up in 10-15 years unhappy in your current professional and then be financially strapped in a lifestyle. Take the road less traveled--try the switch! Right now, with the 7/7 schedule you can move forward with flight training and even working as a CFI so see if this is where you want to go. The only thing you are out is the cost of flight training which is not insurmountable with your income. Just like someone who expends time and money to start a small business on the side, there are opportunity costs. The opportunities right now are greater in this industry than they have for the last 50 years! Live without regrets. This job has many boxes to check along the way (just like med school/residency/etc.) that you are used to completing. Start with flight training. PM if you have other questions.
