Would Kalista Support Work?

When I first started reading Kalista's abilities I thought "Support" before "ADC". I figured her passive item would be for her lane partner, making her an ADC or Support (Or part of a duo top lane). I thought her passive would be great for harassing while staying at least semi-safe yourself. Her Q I figured would be more good harass. At this point I wasn't sure weather she'd be a support or ADC, but then her W happened. I thought her W cemented herself as a support. Having the passive boost to damage for her ADC while also giving vision in the active. Her E made me question my previous idea that she'd definitely be a support. It reminded me of Twitch, and I figured that if she would be a support, this would just add to her style as a high harass support, making a sort of kill-lane. Her R seemed situational, as flinging your ADC or your Support into the enemy seemed like a bad idea most of the time. Unless, that is, you're the ADC and you have a tank support. So, do you think my original thought of support Kalista would work? Or would her move set just not be worth it over some other possible harass-based supports?
