Yes, this works as all current Shimano hubs use the same 10 mm hollow bolt to fasten the freehub body to the hub shell. You may have to fudge to get the dust cover and seals to fit the new body as it probably won't be the same as the current 8/9-speed body.

Along with the redishing, you will have to shorten the axle 4 mm to assure it doesn't stick out beyond the dropout faces.

I'd be tempted to just force fit the 130 mm hub into the 126 mm dropouts. Generally this is fairly easy to do and does no harm.
