OK, I now get the gist of what you are thinking of doing and why it should work. Sounds reasonable on its face, though to be honest, i don’t completely folllow everything you are covering here, and probably won’t without the hub in hand, as it seems a little differently configured than my 142x12 rear hub.
That said, it seems to me you have scoped this out as well as anyone could, and if you feel confident that these mods can be done with a reasonable amount of accuracy and precision, I say go for it.
Would love to see pics of the process, as well and the result.
Good luck!
