Honestly, no.
I've owned rabbits. It's not worth it. Small problems like not eating, not pooping, or even teeth cleaning are affordable, and will likely never pay for themselves if you get insurance. Even including the cost of neutering them if you don't adopt, over their life time most rabbits won't accrue more than a few hundred worth of vet bills.
Rabbits are small animals, and illnesses will kill them regardless of any vet treatment. If you have a true emergency, it doesn't matter how much you pay, they go down fast and die. Coming from someone that has both rushed my rabbits to the vets and let them die peacefully at home, you're better off keeping them at home and letting them die in peace.
Don't forget stress can kill them too. So you have an emergency where they're already at death's door, combined with the stress of being surrounded by people with strange things shoved in their faces and getting poked with needles, they really just don't stand a chance.
I've yet to have a rabbit survive a life or death emergency. It's more merciful to cuddle them in a warm blanket and let them fade away in your arms.
Not only that, unless your insurance covers 100% you're just paying $15 a month, plus a reduced vet bill which when you crunch the numbers at the end of the year doesn't really save you money.
Unless you have an expensive and on going problem, you'll lose more money than you save.
Get the rabbits, see their general health and go from there. Pet insurance doesn't deny animals based on pre-existing conditions. I'd go based on needs, and if it's right for you than a general yes or no.
