Large enough rabbit cage?

This should be fine, although I would have the rabbits separated out. It's not a good idea to keep the rabbits together for a long period of time because they may get anxious and hurt each other. My rabbits are kept in 24x24 cages. If you put a divider between the cage the two rabbits will still be close together in the one cage but have their own space where they won't hurt each other. Good Luck!
