Yep. I have a 7 foot long secondary coilform hanging in my garage I have
to get around to winding this way someday. It is going to be bifilar
wound like you asked with 21 guage, or the equivalent of 15 gauge. As I
see it there are really no benfits, at least not noticable ones anyway.
In my case the main benefit is cost, but winding this beast is probably
going to suck.

Also yes. Somebody use to do this with their driver or tertiary coil on
a magnifier, with instrument wire if I'm not mistaken. I can't think of
who right off though (Bert Pool maybe?). The benefit of this: you cram
more inductance in a small area, but you increase voltage stress,
assuming that you meant series wound and not parrallel.
