No option to slide around some spacers and re-dish the wheel slightly?

Unfortunately not, it's a sealed bearing hub and appears to have a shoulder on the axle that the bearing has to sit against. If it was a cup and cone hub I totally could.

BTW, Winner 13T will not fit on an Alpha body.

I'm overwhelmed by the awesomeness of the response to this post, thank you so much everyone! pastorbobnlnh has a 13t on the way to me!

Wow, this is a spectacular diagram. I assumed it's for the Winner hub body, need to look for one for the Alpha hub body.

I'm gonna guess that since the Alpha-series freewheels had new, subtle cog features added for robust index shifting, Suntour may have not wanted shops tinkering with them with the possibility of the older cogs getting fitted (to the detriment of shifting performance).

So I'm going to say that as I've also never seen one, I don't think that any Alpha freewheel "charts" or posters were ever produced.
