Not sure I quite understand what you're asking. Let me see if I've got it right. You want to;
use custom fanart for your channel? or create custom views? both? or something else entirely?
use your Plex channel to dynamically create .strm files and add them to the Plex library? (fyi: .strm files are not really supported in Plex. They may work in some instances on some setups but that may break without warning or chance of repair).
Is that right? Any more clarification you can add may help to point you in the right direction.
