i would strongly suggest the following idea..
Send your guitar to a luthier to fix the scratch problem. If you are not comfortable with locals, foreign is fine but at your own expense.
Then, find yourself a frame maker and build something like this.
Now lock your guitar in it and mount it securely to somewhere you desire.
Then you'll need some securities to guard it.
You may also consider getting your precious insured.

Remember to insure against fire hazards, natural disasters and most importantly damages on the guitar(eg. fine scratches)
But if this idea sounds offensive and does not appeal to you, i apologize for that.
Whining about fine scratch is so b*tchy..
