Interestingly, here in Boulez, he indeed uses slurs as the phrasing tool. It looks similar to what I would need.
Boulez, Pli Selon Pli 3

This use of two levels of slur seems entirely sensible and clear in meaning to me. However, I'm not sure everyone agrees.

I strongly believe that is the way. If you make slurs ONLY on the main notes covering one syllable it would look completely different, and not so musically.

Interestingly: Boulez writes lyrics under the grace notes, and also has slurs from-to grace notes!
