The spacer kits on a regular wheel will be totally fine. I've been thrashing the ***** out of my SSCX all year and it's an old set of CK Iso hubs with spacers.
I don't THINK you'll have any issues with 9spd chain on a 12spd crank. the fit won't be AS precise as a narrower chain, but with good tension and a good chainline, there's nothing the chain can actually do but be straight.
I have an aluminum Niner 17t that seems more narrow than the steel Surly cogs. But the steel Surly's are basically a lifetime purchase, they're the go-to for a reason.
EDIT: What are you doing for chain tension? Sliding dropouts? EBB? External spring tensioner?
