I have the Ti freehub body still on my hub and still in daily use with over 55,000 miles. If it ever dies, I think I'd replace it with the steel ones just for cost reasons. Durability of the Ti body certainly hasn't been an issue.

Thisone should work. Shimano 105 FH-5700 Freehub Body (w/ Washer and Seal) (8-10 Speed) - Nashbar
Shimano made freehub body swapping pretty easy since the attach splines are the same on most of the freehubs. But if you put a shallow flange body on a deep recessed hub it will bolt up but chances are the inside (largest) cog will rub on the hub or spoke heads. You can go the other way around and the only issue will be the freehub body will extend farther out, but most people will just fit it into the dropouts and go on their merry way. If it fits it fits.
I've said this in the other thread, if you buy just the freehub body, that is not spec'd to your hub, there is an equally good chance the old DS cone and seal won't work. Well, if it fits through the dust seal, the wrong cone might work. I have no experience on how well mismatched freehub body cones/races hold up but I suspect there are a lot of them out there. I know a lot of Shimano cones have pretty similar dimensions.
Wheels mfg gives dimensional differences of their aftermarket cones.
