There's no stopping other editors from making a ROTJ:R Purist Edition (that is taking some elements from it but keeping the original story largely intact).

Just as there is nothing stopping people from making ANH:R or ESB:R Almost Completely Remade Editions (just as long as credit due is given).

We are all playing with the work of the original crews of these films so there is nothing stopping us from reworking each others work too.

I'm looking forward to a real shake up for ROTJ as in my view it's more in need of one than even TPM but the originals aren't going anywhere so there is no need to be precious about any edit.
