In a weird and absurd way it would make sense if the survivor of this standoff simply flies away never to be seen again, since that goes pretty much hand-in-hand with the movie. Their win condition has been met, and they aren't needed anymore.
In an other way the absurd sense of humor from moderators to provide fake evidence (paranoid cops, lynched people showing wrong roles, etc) would make sense for mew to show up as mewtwo when killed. That would give Mewtwo playroom to remain in the game with a strong position as the fake mew. However people have already seen this one coming so this wouldn't work anymore.
Arlee claims every-other-night-doc and says that her rolecard doesn't say anything about being mewtwo when she dies. I'm not sure if Lysah said her rolecard would do this (I can't be arsed to recheck all 12 pages about this now, I red through them as carefully as I could during the night.). By this logic Arlee would show up as mew when killed (unless foxxi + worg feel like being sadistic and messing with us, and turning her body into mewtwo). Then we know for real Lysah is mewtwo and we'll kill her afterwards.
On the other hand, as also has already been stated, if Arlee shows up Mewtwo we're still not trusting Lysah and will off her right away anyway. *shrug*

Let's just get it over with.
I think Arlee needs this one though to remember I love her:
