No, that's backwards. It would need a spacer that is 6mm thicker, not narrower. And only on one side. The NDS never uses a spacer.
If this was a normal hub, you would buy an axles 6mm longer, and add one 6mm spacer to the
drive side only. If the wheel was already built up, it would need to be re-dished slightly. This was a very common bike shop task in the 80s.

Yes, 99.9% of them were spaced for 120. 126/6 speed started showing up in racing bikes at the very end of the decade.
