I don't think is going to happen unless they overhaul the way guests work. They're just simulation "placeholders" right now, they don't actually stand or behave on their own. This used to be in JPOG, but is highly unlikely at this point :/
I love it when they wander into an enclosure
a raptor got out one time and it cornered a hundred guest so they all ran into the enclosure later the raptor and the I- rex were kicking,eating, killing, and scaring the trapped guests
