Hypothetically speaking as an untrained, inexperienced, unqualified and nonsensical wannabe tinkerer here's idea "for somebody."
As I look over this and similar designs it seems to me the biggest roadblock is the bowl mounting/cutout(s) for the metal table. An enterprising person could supply a precut metal top and depending on the design the recipient could make a jigsaw-cut wood top below it to support the metal top. Ideally, a "replacement" Performer bowl in the preferred color or craigslist donor would be used instead of a donor OTS for example, so that "proper" mounting bolts could be used. Either that or a special mounting scheme for standard bowls would be designed and supplied also.
From there, a list of commonly found frame pieces/sizes, legs, wheels, pre-made drawers etc. could "just be bolted together."
