Sign me up. I would much rather get up early, make the kids lunches, take them to school, take care of household, pets and grocery shopping. Definitely not an easy job, but no answering to "the man" and stresses of going to work and dealing with that BS.
I don't see it as immasculating, due to the simple fact that you are doing your part for the family. That isn't always defined as "breadwinner"
