I think the MMM toys could be hits as they were in the 1960s, despite
living in this post-Star Wars era. Besides, towards the end they did
introduce a couple of aliens, though most of MMMs stuff was based on
either real space equipment or pre-Apollo proposed ones, such as this:

I trust Tom Hanks to do a good job representing the franchise. Hey, if
there can be two films about a toy line of alien robots that turn into
trucks and planes and beat the stuffing out of each other, then there
is room for a collection of lunar astronauts who had a really cool base,
a legged walker, a mobile laser cannon, a starship/programmable robot,
and some hover sleds.
