I think a gesture is actually worse. They can say, hey look, I'm just like you. If I can work like this so can you. So buck up. When in fact they can go into their reserved conference room any time they want. Or not even use their bigger cube with 2 assistants. Just get the corner office and keep your gestures.
I'd agree that attempts at such gestures are a calculated risk, and when they backfire the result is worse than doing nothing. But I expect it's at least possible to sell it hard enough that you win over most of the people most of the time.
