I think the permeability is the important thing to find out.
It may be too low.
But, it might be perfect??
@Lidmotor,
Yes, I have thought about jonnydavro's aluminum pie pan experiments too.
Many things are coming together, here.

That is a bunch of light coming out of that little toroid. "More please". What do the secondaries look like? Maybe a little LED version of the JLJL in a smaller box??

I had a hunch that if I did one of them in a way that got much higher voltage that the second one could gett a ride from that and could just be there, so the second is 'scramble-wound' but I kept it all on one side of the first secondary.
That first secondary is something I derived from using the MK1 style, which I have always liked a lot.
I was thinking of 3 phase one day and wondered if I used 3 directions of winds (which is the MK1) and made each segment a multiple or maybe exponent of the first, if I could get 3 phase.
The answer to that was no.
But, what I did get was about twice the voltage from the same number of turns.
I must say I have had really high volts before, but they required a very specific set of elements (to be at resonance) and would quickly degrade and the effect would be gone.
So, one of my criteria is that the bandwidth be wide enough to take a change without much loss. (and this is why I used the xtree in my experiments. It is really stable.)
So, to make this secondary that is in this one I have total 84T.
This number is divided by 7, so 12T go into each segment. Or, x=12
You will always wind (turn) around the toroid the same way but your progression will change.
Start a little to the left of center and wind 12T progressing to the left (actually 13 turns to give you 12 spaces.)
Proceed to the right carefully placing each turn into the 12 spaces. Continue 12 more turns to the right (again add one).
On this final lap you carefully wind 4 turns in each of the 12 spaces.
So, you end up in the center. You can keep the extra 2 or take them off, but I keep them because I usually lose count anyway.
On the big golden toroid (JLJL) I made x=30T but instead of 4T in the final lap I used 8T ... for a total of 330T for my secondary. Wow, I put the scope away at 1400volts!
I am still playing with this, but yesterday put the first one to the test, and it has worked beautifully.
I already made 6 videos on this circuit with multiple secondaries, so I won't be making more until I change the circuit, but if I can make one that works, I will post a video showing this winding method.

I found a source for boxes. They are from ritz camera and unfinished and cheap enough. They are a bit big for the one tiny 10w cfl, and I am thinking, a strip or ring of leds under a diffuser of some kind could work well.
I will make a pic when I have something using the box.
thank you,
