From what I've seen of these things, it's a bad idea:
...the rim usually isn't made properly to allow using rim brakes,
...the spokes are often welded at the rim--no means to adjust or true or replace,
...the bearings are not always easily replaceable, when these wheels go bad you normally just toss the whole wheel and buy another.
If you want bomb-proof spokes, maybe you could buy some spokes+nipples from Worksman and then drill out a hub and rim to accept them.
You could just buy a whole Worksman wheel of course, but having one I would say the braking options are not that great--the (front) drum brake doesn't seem to work real well, even after cleaning. The rear coaster brake stops, but not real hard. The edges of the Worksman rims are rolled instead of flat, preventing you from using regular rim brakes on them.
...Alternately you could get some disk-brake hubs and drill them out and use them with Worksman rims and spokes.
