Concrete is inexpensive, but takes time to cure. If rapid reuse is to be achieved, the concrete needs to survive.

Maybe in future, but not now, and perhaps even foreseeable.
The new concrete type they're using has a cure time measured in days, I believe. Anyway, the OP proposes a radical hardware design change that just doesn't seem practical, for reasons of piping, pumping, and service, as mentioned, and is a lot of overkill to spare some concrete.
Did you see the comparative sizes of the two launch mounts in the OP? I'd call that a radical redesign. You could see the proposed setup from over the horizon.
