9C Continents Fat Bike Axle mod 175mm + shop press?

Can I re-fit a 9C hub with a 175mm rear axle for a fatbike?

Where can I find the right 175mm axle?

What about derailleur and cog alignment?

Is there a way to offset the freewheel and the disk threads?

There are complete 9C 9C clone fat bike kits complete with controller for two hundred bucks shipped.

Sounds cool. Can you please provide some hyperlinks?
