I agree with j&b. I had Tui and Froe with a divider between for (I think) about 4 days and the behaviour changed a lot in that time. They definitely became more relaxed with another bunny being there over that time.
I think the key factor with your 3 is the fact that you're going to be moving, which would have probably upset them even if they were bonded, as it would have been a new bond. Better to keep them as they are and review things once you've moved I would think.
