I had one of these moded M770 cassettes from Walt ([]( and while it wasn’t a 500% range by optimizing the front ring I had a good range, it worked to deliver 5-speeds on a King SS hub and all the cogs were on a carrier so no freehub damage = awesome. Also important, a Shimano shadow derailleur would shift up to the 34. The problem with building a wide range low-cog-count cassette is that the modern Shimano and SRAM derailleurs can only shift a big cog inboard - at which point you might as well have 11x of them?!
