Aiming...
Would be utter hell to balance aiming, 'cos it'd need to change speeds and weapons, and then distances, then trade routes, then...
Cascade effect, it would need everything else changing as a result.
*However* from a technical standpoint, it should be 100% possible to just use different ship models, the new ones being scaled down versions of the current ones. Bare in mind this is technical standpoint only, and is not a viable option for addition to the mod, despite the increased realism to planet/base sizes that it would bring.
