bonding?

I am building a new cage and it will be done in couple hours (drying time) and it is about 13.5 ft.^2 and I’m about to get another female to go with my current female in about two weeks and I have a couple questions. Can I put my current pig in the new cage or should I wait for the second one...

I have two sows and are extremely tightknit, wherever one goes, the other follows, and both of them start their little piggy expeditions! Lol. they both seem very oddly submissive, and extremely, extremely lovable to one another. When they eat they sit right beside each other and rub faces...
