Agreed; if only we had some kind of reference to edit together something like that! Since we have no known record of the actual edit for that film, we can only rely on people's memories. And you know how effective that can be...
(see: people claiming to have seen the Biggs scene or Luke missing with the grappling hook in the first film)
If we had at least a cam copy of the IMAX edit, someone could easily reproduce that in a fan edit. But so far, nothing of the sort has surfaced.
