Rach 2 or Chopin Scherzo 1

[chopinlover01]

So, at my performing arts school, we have senior capstones, a project than involves at least a 10 (preferably 15) minute art component, along with a 35 minute monologue. (35 minute monologue, sheesh. Anyways)
I was thinking of doing one large scale work, and then doing Chopin's Op 10/1 etude as the opening, just to get everyone's attention. Then, Chopin op 10/4 later in the show.
But, for my large scale work, should I do the first movement of the Rach 2, or the first Chopin Scherzo? These are just thoughts looking ahead, I may well change my mind. But, as I practice 3 hours a day and learn new pieces and technical concepts very quickly, both my teacher (a graduate of an english conservatory of music) and I feel I will be ready if I start whichever piece I choose and work on it throughout the year.
The only problem with the Rach is I would need to get an orchestra together, though that's manageable.
To put it in a relative perspective, I am 13 (7th grade) and am doing the Rach op 3/2 prelude in c# minor and beethoven moonlight sonata 3rd movement, Debussy's 1st Arabesque, Bach's prelude and fugue in c minor WTC 1, as well as Chopin's concerto in f minor.
So, all in all, which do you guys think would be better for a large crowd? I've heard them both live and can't decide. Also, do you all think I will be ready for rach 2 at that point if I choose to do so? I think so, but just curious to get different opinions. I'm more than happy to majorly up practice time.

Have you ever "put an orchestra together" before, or are you just presuming it'll be manageable?

This actually would be a few years from now, I'm currently in 7th grade (my school is grades 6-12) and would be doing this my senior year. I have lessons with my teacher year round, and he actually did this when he was in high school.
The etudes are a work in progress. I have the 10/1 about 3/4 of the way through, but haven't started on the 10/4 yet. Don't want to do them too soon, as they will get sloppy for my performance (a habit of mine that I know and hate).
Oh, and for the orchestra, my school has one, but it's not large enough. But in 5 years, who knows. There are also some small orchestras near me who (and I've talked to the managers of said orchestras) would be happy to do it for no charges at all.

I've put an orchestra together two times, one for my Chopin concerto, and one for a Hadyn.

5 years!?? Wow, nice planning, I guess...

By all means, if that is such a long term project, go for a concerto. But I still wouldn't recommend the Rach 2. I'd go for a Mozart concerto, especially his late ones. Or Prok 1. But hey, I'm not you. Good luck with whatever you wish to play!
