What would happen if Mulder and Scully investigated the Blair Witch legend and got lost in the woods like Heather, Mike and Josh did?

That would actually be a funny and sinister story, the Blair Witch Project happens within the X-Files universe, Mulder and Scully are sent to investigate after they disappear and the footage is found, however other FBI agents or police have vanished leading Mulder and Scully to arrive and the witch messes with them.
