A combination of Sickchill, Jackett, Deluge and Plex with one custom script run by Deluge does exactly this for me, on a VPN connection. I search in Jackett, click the upload to blackhole button, Deluge automatically downloads it, then calls a script for Sickchill to rename, categorize and move to my videos folder, and the same script calls a Plex API to rescan the library.
