7 to 9 speed
I have the '09 XT drivetrain, DT swiss front wheel, Fox fork.. might as well make it 9 speed, right? It's a complete frankenbike specialized hardrock from 1999. Fun stuff. Anyway, can I just put a new 9 speed cassette body on the same rear wheel? How much would the drop outs need to be spread? It's steel so I figure it doesn't matter.

You can swap freehubs like Svr wrote, but you may have an issue with the proper fit for the right cone and dust shield. I usually buy a hub on sale, which is usually only about $10 more than a freehub body. Then I scavenge the freehub as well as the cone/shield/spacers and bearings. You'll also end up with a spare skewer and axle.
