wip Nutcracker suite for Piano Duet

This is an arrangement that I have been thinking about doing since winter of last year. No, not because the Nutcracker Suite is common as Christmas music, but rather because the Nutcracker Suite is my favorite of Tchaikovsky's 3 famous suites. Instead of starting with the March as most piano arrangements do, I decided to start with the Overture. I couldn't find many piano arrangements that included this so I decided to go from the orchestral score and arrange it myself. But I ran into a difficulty after a while. No it isn't the clarinet part and me having to transpose it. No, it is the entrance of the entire orchestra. So, I decided to highlight different parts of the orchestra. 2 distinct voices are highlighted the same color because I ran out of colors to highlight with(but you can tell the difference because one of them is almost all 16th note staccatos).

So here are my score arrangement, both mp3 and pdf, and the pdf of the Overture with the highlighted areas. Pages 4 and 5 are where I have highlighted distinct voices in the orchestral texture. The ones highlighted in blue and green I think would be obsolete in a piano duet arrangement, especially the one highlighted in green since it is just the same note being repeated over and over.

What do you think of my arrangement of the Overture so far? I know it is all treble clef but that has to do with the fact that there are no cellos in the overture and it goes pretty high up, high enough to consider me having it in treble clef instead of bass clef. I know I could just lower the notes that originate from the viola parts down an octave and it would fit perfectly into the bass clef but I'm just not sure that I should do that.
