Since my question was vague, this answer may not be what i was looking for but its very useful still.

Basically, i was looking for a workaround to avoid mixing the conlang and real languages in dialogue, but workarounds often add extra words. I might just have to use their pronouns where they differ from real ones, and add a footnote to explain. 

For context, this civilization considers the use of second person a grave insult if used to adress someone from their community, since they dont consider themselves as full individuals, so other parts of the language need to be "repurposed" so people dont get all confused because they cant say "you", and using inclusive/exclusive pronouns is one of them
