Maria would at least know OF Daisy since she was a member of SHIELD for a hot minute pre-WS and she did do one or two guest spots on the show. I can't remember if she and Daisy actually MET face to face on the show, but I think it's safe to say they've heard of each other? And definitely she and Sharon should be friends.
I think everything else sounds good! We can totally toss people together and see how things shake out!
