Similar hair is something Pokemon as a franchise has used very liberally to show familial relations between characters, or even some cases where they're just married and not flat out related by blood. Lusamine and her family is a prime example of this.
Furthermore, you could infer a relation between Ariana and Mars from both their similar hair, and their names. There's an obvious planetary theme with the names of the Galactic admins, but there's a secondary theme that fits will with the theme of DDPt: The Roman pantheon. Mars being the Roman name for Ares, the god of war. In Japan, Ariana was named Athena, named after the greek goddess of wisdom, who was also heavily associated with warfare herself. You could even say Ariana(Athena) is the mother to Mars in the same way that the Greek pantheon preceded to Roman pantheon.
Lastly, Rocket and Galactic both share sort of a space theme. Like mother, like daughter, both of them basically lusting after their respective bosses. Nothing's confirmed, mind you, but there are some loose connections there and it's something entertaining to think about.
