It just wouldn't be the same. Ami would be sincere about the prince and princess thing. The adults would give her funny looks and brush her off. Mostly importantly, Ami has no chance of actually keeping up with Asuma. We have....well, better odds than Ami.
Most importantly, we'd be properly trollish. Go the whole nine yards in coincidental meetings, inconvenient gossip mill (also known as the local spy network), and pushing for team workouts.
Ami, bless her fictional heart, would try but I don't think she'd pull it off.
