There is a bit of a trick to this passage that makes it very playable.
I use 1-2-3-1-2
Using the first LH passage as an example, A,G,F,E,D (the D played with 2nd finger), my hand is already slightly turned, my 5th finger lightly resting on the next grace note G, and my hand opening, the thumb reaching toward the B above (span of a 10th)
By training this way, I virtually eliminate jumps and reaching the 10th from the lower grace note is a mere slight rotation.
IOW, I am virtually ON THE KEY before I play.
Doing it this way, 12312 is the only workable fingering, but you have to train until what I describe is automatic... then you will find the passage becomes relatively easy.
