X dino on Crystal Isles?

[ArrynHellfire]

Hello!
I've been attempting to replace the regular Mosasaurs with X-Mosa's on the Crystal Isles, so far with no luck.

Simply this doesn't work:
NPCReplacements=(FromClassName="Mosa_Character_BP_C",ToClassName="Ocean_Mosa_Character_BP_C")

Also doesn't work:
ConfigAddNPCSpawnEntriesContainer=(NPCSpawnEntriesContainerClassString="CI_DinoSpawnEntries_DevilsWater_C",NPCSpawnEntries=((AnEntryName="Ocean_Mosa",EntryWeight=1,NPCsToSpawnStrings=("Ocean_Mosa_Character_BP_C"))),NPCSpawnLimits=((NPCClassString="Ocean_Mosa_Character_BP_C",MaxPercentageOfDesiredNumToAllow=1)))

I either get the regular Mosa or no spawns at all.
Maybe someone can tell me where I am doing it wrong? Or is it not possible at all?

This is on SINGLE PLAYER
And yes, I am using the DestroyWildDinos command and using -preventhibernation as a launch option.
