I've been thinking about this too, although I idea I had was for a
default field.
List( > 5 ) from collect( Bus( color == "red" ) )
So we could define default fields that can be used in the way you said.
Open a jira and we'll consider this for the next major release.

No - you can use any java object as a fact, so both of your classes are
