You can add 'and yet more exotic again', as morning April 2019 doesn't have Mars either (it's low in the evening sky), and Uranus is at solar conjunction on the 22nd.
So the window that's just about closed just now might be it!
Out of interest, how were you working out the possibilities, as with 2/3 not working out, could there be any others? Though with Uranus increasingly far from Pluto, it will moderately soon become very difficult to get U, N & P in the same sky for a century or two, so I think you're right there! 😮
