Copper magnet wire appears to be more readily available in required quantities as opposed to PVC insulated wire (without buying in bulk minimum quantities) and is already used in step up transformers.
Would magnet wire be suitable to make stretched wire stators from ?
Would there be any drawbacks (cracked insulation from stretching, arcing, vibration buzz, etc.) ?
As for calculating the open/closed area, more of the "closed" area would be copper versus insulation. The same AWG/gauge wire would have a smaller OD providing more physically open area restricting less air flow.
Any thoughts ?
TIA

Depending on the intended operating ranges, PVC insulation can provide benefits. At high levels, dielectric absorption becomes an issue with many types of insulation, but PVC has near optimal volume resistivity in this regard. This is discussed in both the Janszen patents and the Strickland/Acoustat paper "The Technology of Full-Range-Element Electrostatic Loudspeakers".
With proper insulation, copper vs. insulation area doesn't have a large impact, as the majority of the voltage winds up in the gap (not across the insulation).
Similar to your final point, but a different slant on it: from a geometry standpoint, having the smaller diameter can provide some benefit, as more wires can be spaced closer together for the same open area percentage. In most cases, this increases efficiency.
