This is what I meant by using spacers. I've duplicated your two staves to get a feel for what you are trying to do, since spacers work differently when there are multiple staves present. As you can see in my example, I have inserted 3 spacers: between the note and the dynamic, the dynamic and the hidden grace note, and between the hidden grace note and the ending bar line. You might not need all three, but if you experiment with their sizes, you can see that they interact and each have their own influence on the hairpin's appearance. Note that they will look different in edit mode versus view/print preview modes.
