Rear window wiper? Anyone done one?

[NJM73]

Been doing some searching trying to find if anyone has stuffed a wiper motor into the hatch of a burb. I was thinking about trying to do it, living on wet gravel roads makes my rear window impossible to see out of after a day or so. I had a cherokee as a kid and i loved that feature, did some looking and i think that style might be a bit large to fit and make look good. I've seen a few universal wiper kits, with small dimensions, but only have a 90 degree sweep, which might be enough. Wanted to see if anyone else has done this or seen done.
