Someone to arrange Mozart K411 into a piece for keyboard solo

Mozart KV411 (also k484a) an extraordinary 5 minute adagio for clarinets and basset horns.

I need someone to turn this into a relatively simple piece for two hand piano/ keyboard solo. I will upload a copy of the score but it is readily freely available online. A piece of software will easily transcribe this into 5 individual piano lines in Bb (melody scanner will do it online (and you can take out any of the lines) but you will probably have your own - sibellius or some such).

So the job is really to take those 5 lines and turn them into a piece of single keyboard music. Where the chords become too unmangageable you are welcome to simplify (I am happy with quite a simple keyboard piece) and you may want to transpose one of the treble lines to the bass. But please try to preserve the extraodinary harmonies including the dissonances.

There is only a small fee so it is ideal for someone with the right software to take most of the slog out of it-
