How to name a brother and sister named Wan?

The five characters of "Wanhua *" are "water and water *", and the eight characters are like earth and gold, so the third word and five elements of the name should be gold or water. The following names are in my favor, with high scores in math and physics. You can choose your favorite name from them:

Wanhuaying (7 1) Wanhuabai (7 1) Wanhuahui (7 1) Wanhuaxian (72) Wanhualuo (7 1) Wanhuafu (72)
