Given an NPC/Weapon/etc: swap in texture alternative(s).
If targeting an NPC, it would insert as an alternative to all the LLists it is a part of.
If targeting a single LList entry, it would just affect that one LList.
For probability:
Can be set to "Share" the existing probability of the original NPC. This means the NPC as a whole (no matter the texture) will still spawn with the same overall probability.
Can be set to match probability, but be considered a new entry. This will modify the spawn probability compared to other unrelated things on the LList.
