I personally want to see Hope use her magic while in wolf form so she'd be able to have access to both sides at once, without having to turn into her human form to cast a spell (by speaking or waving her human hands like all witches do). The only way this could be possible would be through her roaring or howling. For Example if Hope wants to pain inflict a target while in wolf form all she need to do is howl or roar and channel her magic though her howl/roar/voice and her target would start to scream in pain (she could even expand this pain infliction spell using this technique so she could attack multiple targets at once) or if she wants to set something on fire in wolf form she just howls at the target and it catches fire, and the same would go with most spells. Say the incantation in her mind, and scream/roar/howl and it works.
I wouldn't like this only because Hope is already so powerful and it seems a little bit too much to have her doing magic while remaining a wolf. I'd rather we see her stay human but maybe she goes into werewolf mode (with just the eyes and enhanced features) and use that anger/rage to fuel her magic so her spells and powers are stronger if that makes sense.
