OP, I left the Catholic church about 20 years ago. I had many reasons for doing so. I respect your conviction to follow your thoughts and feelings where they take you. God gave us free will.
My question for you is: what are you looking for? Are you looking for affirmation? Are you looking for a sense of community where people are affirmed for their choices, whatever they may be? Do you want to exercise your own will and be supported? Is that what religion means to you?
Or are you looking for the truth, whatever IT may be?
From your very thoughtful post, I sense that you are looking for God, the Creator, and that you want a relationship with Him. You're not satisfied with just finding a collection of like-minded people who sing the same songs and worship in a familiar liturgy. You want something real.
Because honestly, why would you waste precious family time and resources on something that's just a loose fit with your ideals? Just for show?
Why not start at the beginning, rather than trying to fit your family into something that feels good? Reread the Catholic catechism. Read Mere Christianity by CS Lewis. Watch the new PBS documentary Catholicism. Research the faith you reject. Do you really reject it, or do you reject what you think it is? Do you know what the Church really teaches about gays, about the role of women?
Here's a blog post by a gay Catholic man. He is very frank about the Church's position, but not in the way you'd expect:

Your relationship with God is important. It informs everything about your life. When your children ask you questions about God, you will need to actually believe your answers.
I started my research when my kids starting asking questions. I couldn't fake answers forever. And the answers led me back to the faith I had rejected. I think of myself as a "prodigal daughter.".
No judgment from me. God's love never changes. He is holding your family close. God bless you.
