SpaceX's Raptor engine uses full-flow staged combustion with methane fuel - incredibly efficient but complex. Could this advanced design be scaled down for small satellite launchers, or is complexity the enemy of small rocket economics?

Additional Context

Raptor engines achieve ~330s specific impulse and exceptional reusability, but require sophisticated manufacturing and control systems. Small rocket companies choose simpler designs for good reason - but what if the complexity could be managed through automation and standardization?
