Problem:
A slur will collide with the "3" of a triplet when its direction is towards the stem.
If the slur direction is inverted it will start by default from the lowest note of the chord member, which is not what I meant.

Using two staves is a half solution, because then the slur will penetrate the nearby chord member (F). Not so elegant especially in this case where it happens to be a hollow note.
So I wonder if it's possible to alter the slur placement versus notehead, (left-right-center). In this case the option "slur placement/right of notehead" could be a solution.
A muted headless whole grace note can help !

Good idea, thanks Richard.
Inter-note spacing is asymetrical now, but it can be easily corrected.
Thanks again

It is easier than that. The grace note can be Visibility:Never
