Part from Korean Trait wich adds +2 Science to the great engineer tile improvement wich might help you

<Trait_ImprovementYieldChanges>
<Row>
<TraitType>TRAIT_SCHOLARS_JADE_HALL</TraitType>
<ImprovementType>IMPROVEMENT_MANUFACTORY</ImprovementType>
<YieldType>YIELD_SCIENCE</YieldType>
<Yield>2</Yield>
</Row>
</Trait_ImprovementYieldChanges>

Sadly I cannot help you with the great engeneer modifier since I am a gamer not a modder.
But maybe Babylon's Trait could help you for a compromise:

<GameData>
<Traits>
<Row>
<Type>TRAIT_INGENIOUS</Type>
<Description>TXT_KEY_TRAIT_INGENIOUS</Description>
<ShortDescription>TXT_KEY_TRAIT_INGENIOUS_SHORT</ShortDescription>
<GreatScientistRateModifier>50</GreatScientistRateModifier>
<FreeUnit>UNITCLASS_SCIENTIST</FreeUnit>
<FreeUnitPrereqTech>TECH_WRITING</FreeUnitPrereqTech>
</Row>
</Traits>
</GameData>

besides changing the spawn rate of scientists there are two lines that give a greate scientist for free after writting is discovered

<FreeUnit>UNITCLASS_SCIENTIST</FreeUnit>
<FreeUnitPrereqTech>TECH_WRITING</FreeUnitPrereqTech>

And pls dont hate me if this doesn't work
