Has any company ever made or designed a converatible minivan?

i have seen countless concepts of weird and wacky minivans from different manufacturers. I think for production models I think there is a australia-only toyota hiace that can be a converatable but im not entirely sure. However, the aftermarket is always worth a try and taking a regular minivan into a bodyshop to make it a convertible wont hurt ;) (although it will get pretty pricy doe)
