You can't space a fixed cog on a proper fixed hub; there isn't enough thread left for the sprocket to properly engage (so the threads will strip) and/or the lockring won't go on.
Crimping the chainstay (basically squeezing a long dent into it) is common practice - most MTB frames are already crimped on the inside for tyre clearance or the outside for chainring clearance. If it is more than a tiny dent I'd get Argos Cycles to do it.
There are, apparently, no 36h black fixed hubs in existence with a wider chainline than the Goldtec. I may have to go the bolt-on route, which would be a shame as I like Goldtecs (I've been using one on the track bike for years).
I know people are running Inbreds with Goldtecs, but the older Inbred had slightly more chainring clearance.
