Is it possible to buy a new Shimano 11sp freehub body and fit it to a old 10 speed FH7900 Dura ace hub?

Nope, i spent a while looking into this and couldn't find anything that didn't require bodging. So my 7900 hubs will be remaining on a 9 speed bike. I bought new 9000 hubs for the 11 speed bike.

Only way is to use an Edco cassette.

Or you can use the 11-34 Shimano road cassette. That one is designed to fit onto 8/9/10 speed freehubs.

Or you can run 10 of 11 cogs from an 11s cassette. Yes, you lose a gear but at least it can keep it in use.
You can't be a real country unless you have a beer and an airline. It helps if you have some kind of a football team, or some nuclear weapons, but at the very least you need a beer.

Or you can modify the existing hub to fit 11 speed. How to can be found on this forum.
