I'm not sure exactly how I would use a Byers worm set with the Newport stage. I've been afraid to take it apart, but it looks like the teeth for the existing worm are integral...

I wouldn't take it apart, either. The model I was thinking of was to attach to the mounting face on the side- essentially it would be externally driven with the internal drive unused and its gearhead removed. And that was what started me thinking it might make a lot more sense to use this as a Dec drive, where constant rate isn't a requirement. In that case, you can use another bearing for the RA, whether you go GEM or fork.

Taking one of these apart is a big deal- just changing the location of the limit switches on one has meant calling in riggers to pick an entire 3 axis stage up and put it on a pallet and ship it back to Newport (surprise! Even minor mods aren't minor).

So leaving well enough alone and using it as a Dec Axis is making a lot of sense to me at the moment.
