grace-note spacing and triplets

[Jan-Peter Voigt]

Hi all,

I have a problem spacing grace notes under a series of triplets. In the 
example, the grace notes produce a big gap between the tuplets or 
collide with the accidentals.

As this situation is evident a few times, I will probably use 
extra-offset and place either the grace notes or the accidentals aside. 
So my question is, how would you typesetters solve this case?

TIA
Jan-Peter
