What you are proposing is to create a multifilar winding. Bifilar
windings (two wires in parallel) are relatively common. I've seen
magnet wire offered with 4 conductors bonded together. No reason you
couldn't do 6.
If you arbitrarily number your wires 1 through 6, just apply power to
the start of winding 1 (W1), connect the end of W1 to the start of W2,
the end of W2 to the start of W3, and so on. Power comes out of the end
Only downside is if there is a thick insulation jacket around the
overall cable. It will take up space and trap heat. Also, generally,
jacketed cables are more expensive per net foot of conductor than a
single conductor. Still, if you can get the stuff cheaper than a roll
of 8 Ga THHN at Home Depot, go for it!
