Sultans would actually sound pretty cool acoustic, if you slowed it down a bit in a sort of bluesy "Layla" style.
Money for Nothing would sound crap unless you gave it a similar blues transformation, sort of like the intro they did for it on the 2001 tour.
Ditto BiA. You really need the sustain of an electric guitar for those solos to work. Listen to the Metallica acouctic cover from a while back for evidence of this.
