It might work.
Might also rust.
The biggest problem I can see with a dog kennel: weasels and ferrets would be able to go right through it. That wouldn't be an issue if you were there with the rabbits, because they would just stay away from you. But it would be an issue if you were trusting the fencing to keep the rabbits safe.
For keeping chickens safe from digging predators, a wire apron can work well. It's just a piece of wire mesh on the ground all around the pen, on the outside but attached. Predators usually try to dig right next to the fence, but they run into that wire, and they don't realize they could back up and dig under.
But a wire apron outside would not keep rabbits in, although one on the inside might.
I think I read somewhere of a rabbit-run with stone or concrete pavers for the base, and plenty of bedding over that. Of course that would be dig-proof in both directions, but then it's more like a cage with a solid floor, with no access to dirt or plants (unless you then shovel a bunch of dirt on top of it.)
Trying to make a predator-safe, escape-proof rabbit pen is difficult, which is probably why they are so often raised in wire cages (although of course those have other disadvantages.)
