I agree with Will about not enhancing the range of her AAs. In respect, Keyhole's purpose is not for damage but for vision. Either for detecting wards and stealth, or to allow Imoen to scout the jungle for ganks or even for potential prey.

Imoen also has her E "Hushhhh!" to perform long range attacks, as Keyhole does not mention that using abilities interupts Keyhole's performance. This is beside LBP's comment below that Imoen's main of damage should ever be her AAs.
