etc.

It should be noted that Stephen's wire has a pleasantly high tensile strength as historical wires go. A while ago I restrung an old (1961) Flemish instrument by my father with four register slides, and I had, for example, no trouble with the four foot in the treble where the gap is ridiculously too wide. The strings on there previously were modern steel. P-wire made no problems in the area (more than a semitone of a margin, in fact). Of course, these are the thinnest, relatively most resilient gauges...

I'd suggest you talk to Stephen, send him the scaling, see what he has to say.
