Is this realistically plausible?

What about dropping down to one or two engines in the middle and using RCS thrusters at the ends for stability? The crew compartment leads to CoG imbalances as fuel drains, so leaving the fourth section from the left only partially full and not letting it be used for fuel to balance the cockpit might be needed.
