Making non-meta ap junglers more meta, like what you did with nid and tal

Ap junglers are mainly in the area of ap tanks with the exception for elise, nid and now tal. what about diversifying it a bit more and making the more non-meta ap junglers more viable in the jungle, specifically looking at Diana. Shes such a niche pick in the mid lane and giving her some tuning could make her viable in the jungle. Things that could be change is e interaction with jungle camps, or an e q interaction giving her more complexity instead of being a linear play style champ.
