We have a majority of the furniture, my friend makes clothes and bedding and such so id put a registry for the little things like bottle and such.

Should be fine only thing is no one is gonna know the gender ahead of time so they may not get the baby many clothes cause I know where I live gender neutral clothes are hard to find but it can be done. I'm doing a gender reveal/ diaper party and everyone is just bringing something at the hospital when the baby is born.

sure but you might ask for gift cards
