You would end up with the nett inductance of single layer coil wound
with the same number of turns. Why? Because if I understand your
wiring scheme correctly, opposing currents in two of the wires
effectively cancel each other out.

If understand this bit correctly you are applying a voltage across a
single layer solenoid with three wires connected in parallel. I don't
see why there should be any current flowing in any other path.
