Tattoo Addition/Cover Up Design

This is what a business in United States was looking for in their tattoo design

I want a design that incorporates the following:
-Number “7” because we have 7 kids and maybe include their names if possible (names not a must)
-Maybe below the existing circle of the tattoo, have waves of some kind (and also could include mountain ranges (the waves can frame the current circle and expand the tattoo lower, or be inside the existing circle)
-I’d like to cover up the existing writing and cover up the cross (or use it in a new design to make it far less prominent, or convert it to the number 7 or something else)
-The current circle shape will have all letters covered and could be used for a moon or sun to complement water and mountains.
The top photo of cross inside the circle is the existing tattoo and the other photos are concepts and ideas to potentially incorporate into the cover up.
-The black cross cannot go away so we need to “cover it” and incorporate new design. Read more
