Is there any way to convert a Photo library to an Aperture library?

I’m asking because i would like to upload raw files from a slr into an ipad. If I do any photo development in Photos for iOS with the iPad for these raws, i can import them into Photos for OS X. I would like to convert the Photos library with the raws to an Aperture library. Then import the converted Aperture library into Aperture. Does anyone any hacks or method of doing this.

Thanks!!!!!
