Sounds doable. The only problem with that type of slider is that you can't use the cotter pins anymore unless you have the type of setup like the woodcraft where the screws that hold in the delrin slider covers are also doubling as nut retainers.
My own foray into DIY sliders has been on other bikes, (supermotos) but only those that had hollow axles. In that case I've used threaded rod with skateboard wheels. You have to be picky about the wheels though and get extra hard wheels because regular urethane grip too much.
