I've seen some great looking, simple quilts using the type of fabrics you've gathered. A non-traditional flying geese (make all three parts different) looks great. I myself wouldn't go with just bricks. A few angles adds interest, I think. But that's just my opinion. You have to do all the work! That disappearing 9-patch works well with the large prints, too.
I'm sure any girl would love whatever you come up with.
