[Grammar] hardly+perfect - future situation

[tyrp]

We were taught to use the past perfect structure with 'hardly' in sentences like:
Jenny had hardly opened the door when her dog knocked her down.
So what if we make the situation future? Which of the examples below will work best or had I better use something else to sound more natural?
1. Jenny will hardly have opened the door when her dog knocks her down. (I give my vote for this one, but I'm not sure I'm right)
2. Jenny has hardly opened the door when her dog knocks her down.
3. Jenny has hardly opened the door when her dog will knock her down. (I don't like this at all as it has a future tense in the clause of time and condition).
Thanks a lot in advance. Hope for your help as always.

This future situation is so unlikely to be spoken of that we actually don't think about the tenses we might use if it were to happen.

There're more silly questions than there seem to be answers) Sorry for this one and thanks a million for your help and guidance.
