At this point dipping a single level of monk for SH seems like an excellent idea for the AC bonuses from wisdom, and since her dexterity is pretty good too you might just consider keeping her a monk fulltime. I think it's also a nice fit for her personaltiy, she is obviously very devoted and focused.
Now Astarion, I have problems with. He looks faaaaar too buff to have a STR of only 8. I'm sorry but you can't tell me that Astarion can have that body and an 8 STR, especially after first meeting me he basically managed to pull a knife on my throat after dragging me to the ground. It just doesn't work.
Also, Astarion having a 10 CHR is ridicolous, he is all about trying to string you along and he is quite convincing. Drop his INT back to 9, and give him Charisma instead. Alternatively increase his Wisdom further to represent that he has common sense and foresight. Given that he is a predator, the assassin specialization is way more authentic to his character then Arcane Trickster anyway, so INT is really wasted on him.
I like SH's change, but for Astarion I recommend:
STR 10-12
DEX 16
CON 12
INT 9-10
WIS 14
CHA 12-14
Astarion just can't conceivably have less then 12 Charisma, it simply doesn't fit his character. Likewise, dropping his WIS is not going to work, because he is far too practical for it to be just average. Reduce his INT, and CON, boost his CHA, and see if you can bring his STR up to 10, because again, with that body, he can't have an 8.
