Some of the super8 prints were done a lot better than the 16mm reductions. Derran and others managed to get Super8 prints mastered from the same source used to strike the theatrical prints, which means although you get the lower resolution of Super8, you get all of the detail not eaten up by the grain - and the full exposure latitude of the film.
If you can find a 16mm print taken from that then it would be truly amazing, a super8 print could make a great DVD transfer, but it wouldn't be worth trying a HD transfer, the grain eats up the LOD.
