Earlier monoplanes could pull British fighter development forward

What if the Sea Gladiator and Hawker Fury had been monoplanes?

Britain would gain monoplane experience earlier and could move one or two fighter generations ahead of the historical path.

The Hawker Fury sits on a development path that leads toward the Hurricane. If Fury and the Sea Gladiator generation were already monoplanes, British designers and operators would acquire experience with the new layout earlier. That experience would affect structures, engines, handling, and the specifications written for successor aircraft. The change would be a generational leap with compounding effects rather than a direct one-for-one substitution.
