H2 conversion...
I, too despise dump bags with a passion, and thus have done several Heritage II bag conversions on older Kirbys. The first was a Heritage 1HD, factory equipped with a dump bag. I initially just swapped a complete Heritage II (H2) bag assembly onto it, which worked great but just didn't look right with the gray outer bag and gray plastics. I eventually replaced this with a proper orange outer bag, thanks to a generous fellow Vacuumlander, retaining the H2 mini emtor and fill tube, to give it the proper look. I did this again with a Heritage '84 that had a type 2 bag system because I couldn't get the original emtor and fill tube assembly back on after I laundered the outer bag. I had really wanted to use the type 2 setup on that one because I have a small supply of type 2 bags I wanted to use up. The last one I did was a Classic III, on which I replaced the original red tartan dump bag assembly, which looked like it ought to have come with a bagpipe accessory, with a Legend II bag assembly. This is identical to the H2 setup, except the red and the gray on the bag pattern are reversed from the H2, making red the more dominant color, instead of gray. It looks quite nice with the red Classic III bag topper installed. I had actually considered doing this with the first 1HD I retrofitted, and likely would have done so, had I not been able to source a proper orange bag.
All that said, I suppose, if one had the requisite sewing machine skills (I certainly don't), and one could find some fabric close to the right color, weight, and texture, one could sew a replica bag with a zipper, using an H2 bag as a pattern, and either taking the spring coil from it or sourcing one for an F&G setup, to finish it off at the bottom to make a more original looking filter bag setup.
