not that i've seen. some have said there are places willing to do them, but i don't know if that means it's a good idea. i think the structural integrity of the roof is a concern, you can see the shape doesn't lend itself well.
I don't think I would do it. I know years ago that putting in an aftermarket sunroof resulted in a number of leaky disasters. The technology and materials are probably better today, but I would still be leery unless you got an iron clad/long term guarantee of no leaks. It's probably why getting a manufacturer's sunroof is so expensive.
The Prius C has the same exact roof line as the regular Prius and I see a lot of those cars with the optional sunroof.
