Probert's Enterprise-C design leaves the outcome unchanged

What changes if the Enterprise-C uses Andrew Probert's original design?

The ship would look different while retaining the same intended weapons, capabilities, and fate.

Andrew Probert's original Enterprise-C design would change only the ship's appearance in this scene. Its intended weapons and other capabilities are treated as equivalent to the version shown. The encounter therefore unfolds the same way, and the Enterprise-C is still destroyed. The counterfactual changes the production design without changing the fictional battle.
