They should cancel it. And create a TSTO (Two Stage to Orbit) space plane system. The first stage being fully reusable. With a major focus on quick turnaround, like 1 hour of post-flight inspection and refueling, then back in the launchpad again. There was a slick Soviet design for a rocket system, that had 4 boosters with swept wings that glided back to base. I think the core stage also glided back to base. Although this design might be obsolete, now that SpaceX has proven their suicide burns.
