Forget Spaceballs II. They should make Spaceballs III(or 4): The Search for Spaceballs 2. This way they could bring in a totally new cast.

I strongly believe that if John Candy were still alive, they would've made Spaceballs 2. They would've done it around now, and made it a parody of The Force Awakens. The Schwartz Awakens, as you say.
We'd get to see an older Lone Starr and Barf step back on the Winnebago, have Lone Starr say, "Barf, we're home."
The villain would be Dark Helmet's father's brother's nephew's cousin's former roommate's descendant.
And instead of finding Luke Skywalker, the map in this movie would lead right to Mel Brooks. We'd see HIM on the cliffside, long beard, world-weary face, even a robotic hand for the hell of it. Like Force Awakens was about finding Luke to restart the Jedi order, this movie would be about finding Mel Brooks and getting him to come back to making movies again.

I think i would have gone for the title: Spaceballs 2 - The Schwarz Awakens
The Spaceballs 2 movie:
