I loved the psychedelic VR-game forced nightmare, making it a shared hallucination balanced by majority makes room for a lot of unique scenarios and interactions. It could even have ramifications for future adventures with possitive and negative side effects, and I love when returning characters have been changed in unique ways.
On the other hand, thinking about a chain of one shots, I'm not a fan of the mind wipe intro. It makes it hard to insert mid way and it puts too much pressure either on the player to do something on the spot or the warden to give them motivations that would clash with the mission right near the end, with no time to let the players do something cool with or about it.
Considering how the animal civil war also doesn't shine as much as it could, it's barely a backdrop, I think that maybe you have two very strong modules here. One about being a mind wiped infiltration team and one about crossing alive the psychedelic war trenches, both beautiful things I'd like to run but kinda weaker when mixed together.
