As mentioned, the result is a wheel that isn't what we'd call "good".
However, if you aren't too heavy and are somewhat easy on the wheel, it can still work.
I've stuffed a 9 speed into my 126MM spaced RockHopper and use it.
However, I only use it on smooth pavement and avoid driveway lips etc. in any manner that gives a severe "jolt".
What you want to do is use the LEAST amount of spacer possible on the DS.
Add as much spacer on the NDS as possible that will still allow you to force the wheel between the dropouts.
IF you can find lock nuts with the "beveled" corners, that helps.
Your Free Wheel won't be a standard distance from the drop out, so you won't be able to swap a wheel in and have the RDER line up properly, since it has to be set to utilize a different area of travel. Ditto about swapping your "custom" wheel into another bike.
Another draw back of your conversion is that the axle is even more likely to bend, since the unsupported distance between the bearings & frame is even greater. Not good if you are a "hefty" rider or hit pot holes.
