Dear Patty:
I didn't play this particular piece, but I think I know what chord you're talking about.
Anyway, I'll leave a particular solution to someone who have more intimate contact with that piece.
I want to comment on something very little considered about chords, but I guess (and submit to considerations) that is very important: which is the musical result that you expect? Do you want a block, an arpeggio, a broken chord, or what? Maybe, the question could be: what do you think the piece requires of that particular chord?
So, with that answer, you may just pass over details and solve the chord TO yourself. This may include the omission of a note, or whatever. It's very important in that approach to be coherent musically and to understand the harmonic content of the piece.
Please, notice that I'm not apologyzing the absolute freedom of performance, like jazz to say. And it's nothing about "easy" versions, because if there are too many of these individual aspects that should be changed, maybe the piece is over someone's possibilities.
Practical examples: a children that plays Chopin opus 28 n. 7 sometimes just can't play the right hand chord of bar 12. Why not cut the A#-3? There is an A#-4 and the overtones of F#-2. See? It's just one note, and the children in question may play the chord and there is no significant change in musical result.
In the other hand, the Preludes of Debussy, for instance. You found so many large chords, in progression one to another, that if you can't play them, better let it go. The same applies to some Brahms (and the nightmarish left hand of some pieces by him).
Hope it can be helpful. Of course, there is a value judgement of doing that, but is such a small revision that I think there is no problem at all.
Best wishes.
