I have just come upon another literary instance of this type of Gapping, involving the ellipsis of a modal only, in a very famous novel published in 1951. In the quotation below, "might" is elided between "the moon" and "go up":
"You could feel the war getting ready in the sky that night. The way the clouds moved aside and came back, and the way the stars looked, a million of them swimming between the clouds, like the enemy disks, and the feeling that the sky might fall upon the city and turn it to chalk, and the moon go up in red fire; that was how the night felt."
– Ray Bradbury, Fahrenheit 451
