I don't think you've thought this through. You would have to remove both a 1.6mm cog and a 2.2mm spacer. That far too much additional space, unless you move the 2.2mm spacer behind the cassette. I doubt that you could screw the large cog limit screw in enough.
The only sensible cog to remove would be the 16T. If you do that, the 15-17 shift would be poor.
I'd have to look at the exploded view of the hub to see exactly what positions the freehub. Figure that out and then you could determine if a 1mm spacer would be enough.
I'f also ask if you've actually tried using a 1mm spacer behind the cassette. The smallest cog never has full engagement with the cassette body splines. What matters is that it have some engagement, after the lockring is tightened.
