I have the VHS set of The Godfather 1902-1959 The Complete Epic which I transfered to DVD. There is also a version called The Godfather: A Novel for Television that incorporates much of the aforementioned movie plus additional scenes found in the deleted scenes in the DVD trilogy set. The Novel for TV has never been released on video.

A complete fan edit extended cut could be made using The Restoration and deleted scenes. (I assume that the new, upcoming DVD set (The Restoration) will include the old supplemental material as well.) Until it is released this fall, there's really no point in attempting a fan edited extended edition. Why not use the best source materials for this extended cut?
