My family sort of did a similar naming system. There are 10 kids in the family, but 6 of us have "ee" in our names:
Paulee, Treena, Cindee, Kimberlee, Sallee, Jamee
It's not really the same thing, but it's kinda fun to tell people...
Poor Jeffrey, Steven, Angela, and Danny. Really no way to add "ee" without making it too weird. Haha
