Debussy and small hands - Help!

Hi there,

I was hoping for some advice on approaching playing Debussy's Prelude, La Demoiselle Elue.

I have very petite hands are am unable to play the opening chords as written because there are 10th's in the LH. 

I am able to play 8ve's and can play 9ths on the white keys but struggle beyond this.

I have been experimenting with rolling the left hand notes or playing the fifths together with the right hand chords and then playing the 10th slightly delayed.

It's difficult to know what to do as the open chords are so distinct. 

Does anyone know if there is a recommended approach for this song if you have small hands? 

Thank you so much!
