You could replace Chichi with her in a second image. It would also be all Saiyans that way.
Btw, if you do include Gine, please keep in mind that the Jaco manga art is quite different from the DBZ manga art. In Jaco, all the characters look really slim and scrawny (compared to dragon ball z), which is something you wouldn't see in DBZ. What I'm saying is, make her look a bit like Fasha (i.e. don't give her worm-like limbs).
