Weirdly, it kind of reminds me of the titan transformations in Attack on Titan. Eren needs both a clear goal in mind and the ability to harm himself in order to transform. I imagine Requiem is something like that. Giorno would not only need the arrow to transform into GER, but also one very clear and specific goal for Requiem to achieve.

Though, due to the nature of GER's ability, I'm not sure if it could be tricked. It can defy and/or control fate, as you said, and can even defy fate better than other Stands that defy fate. That said, it's definitely not something Giorno can use repeatedly. I'd still argue that GER is more powerful than Made in Heaven, even though MiH is permanent and GER isn't.
