Script Request: Make Open Chords.

Dear Scripters,

Here's my wish:

Let's say i have a chordprogression in Midi Editor.
It's made of simple, "dense" Triads.
So, minor triad has interval 3>4
And major triad has interval 4>3

Now i want the middle notes of all triads in this progression be transposed 1 octave, making
all triads more "open"
The wishfulscript should do this.

Even more, when i have a chord progression made of all 7th chords,
the script can transpose all second notes in all the 7th chords 1 octave, making all 7th chords more
open.

Bottom line is:
A script that can transpose all the second notes (is that called second degree in music language ?) in triads or 7th chords, 1 octave, in Midi editor.

Willing to pay generously !
