Based on the pics, cages are 16 by 16in in size, very small to me. The floor is also hardware cloth, so that would need to be changed out. Depending on how they put the pens together, that might be a massive pain in the butt to do.
They may be divided by the wood, remove it and get bigger? Might be great if that's true. But the only doors are on the top, and the whole top opens by the look of it.
Wire is chicken wire, no good against predators.
All in all, the worth would be in the rabbits, not the hutches. Unless you loved the rabbits, I wouldn't. No idea how many there actually are, only one with papers, it seems.
