We pretty much do this, although it's a little subject to the same thing that "unlimited PTO" is - one person may feel guiltier about spending money than the other and it may crop up in various ways.
The only thing we haven't quite figured out how to account for yet is that we are occupying pretty 'conventional' roles by choice and by practicality. I can make a lot more money for many reasons, most of them have nothing to do with me, and they certainly don't have /anything/ to do with me working harder or being more valuable than my wife. It is what it is, and we mostly are okay with it.
However, because a ton of my wife's work is still unseen and undervalued (by society, and sometimes by me) and even though we have both agreed that she shouldn't work a low paying job she hates just for the sake of working, and even though we both see that much of her labor is in the traditionally feminine realm of home-making, emotional support, maintaining social connections, etc (which are all very valuable! They make my life immeasurably better! I couldn't afford to pay for them at market rates!)
So our arrangement works well for us if we stay married of course, yet if we don't, I am arguably in a much stronger position of being able to make money, still have an intact work history, etc etc. Yes historically this is where alimony comes in, but it is still hard to grapple with. You never want to think about your relationship ending, yet you also want to work together to make sure that the choices that you have both made that work best for you while you are together don't become something far worse in retrospect if you choose to part.
It’s a very real concern that really comes to a peak when you get older. My mom, as well as my wife’s mom and step mom really felt the pressure of being financially dependent on their husband once they got to their 50s and 60s. It’s not only the lost earning power—even social security forces you into dependency, since your benefits are keyed to what you earned while working. The one with the most peace of mind now seems to be my wife’s ex step mom, who never had her own kids and maintained her career the whole time.
