Yes, the disassembly and, probably, the rewind, ,if needed, would be very simple.
The wire color is neutral.
Some folks say it was green initially. I might try to look at the inside coil to see what color it possibly was.

But the wire is not a litz. Even though I've seen some places calling a silk-insulated solid wire a litz, litz is by definition multy-strand, with each strand insulated with varnish to prevent skin-effect. This wire is a solid core type. Actually made it easier to twist and solder where it broke.

This is a litz I have. I still have two bobbins at work, but many are back home as they at work suggested discarding it, and I told them I'd rather take it for myself. Crazy. Each bobbin is a few hundred bucks.

   
   


The color is a bit off.
But it is a true litz and would probably make  a better coil, not that it would make much difference in this case.
