Of the initial names you posted, I think Willow Aveline sounds amazing!
Out of the combos, I like Willow Evangeline (I prefer this to Willow Angeline), Willow Chantal (I never see that name on these boards, and I've always liked it), and Willow Miranda (I prefer this to Willow Amanda).
I still think Willow Aveline is your best bet, though.
