Hi
Does your family have it’s own heraldic coat of arms that you could balance out the other shoulder blade and beneath that you could have a motto underneath.
It is quite difficult to make the piece a whole tattoo as it is nationalistic/heraldic in nature and is a standalone piece.
Perhaps you could look for any other symbolism of your heritage such as a red and white lion (symbolises the house Wagner was born in) etc
