I don't see the issue with Kepler being like Donatello, considering Donatello was only able to be used because he was included in a group, which Kepler could work with easily. And I do agree Michael Collins isn't as known as Neil, but that's the same thing with Kepler/Donatello, in that he's a lesser known figure being worked into a group. Sagan could be worked in as another cameo on the Astronomers' side, too.
