I love super 8. Kodachrome 40 in particular was basically the perfect film stock IMHO. About 20 years ago I shot a feature film-a drive in action flick-on Kodachrome 40 super 8, transferred it to svhs to edit since it was the old days before NLEs. You can see the trailer here:https://vimeo.com/37537884
Been editing old SD mini DV footage for another feature as well and it's quite easy to get the super 8 look with it. After upscaling you are about halfway there.
