Even though you can't implement axial tilt for Uranus yet, Moon Planes are tilted :P
Good old retrograde Triton's orbit and elongated Nereid's
Not done Pluto yet because I'm not sure how to deal with barycenter system.
Technically I can make Barycenter itself a tiny massless body and let Pluto and Charon orbit it
but it would look funny...
I think it could look good enough for now, the only problem would be the body shown in the map, but I think it's worth having a binary system
