Heartbreaker Zoe?
Of all candidates in my opinion, Zoe seems like the perfect choice for a Heartbreaker / Sweetheart skin.
She'd have obviously a light and hot pink tone to her effects.
Her Q would be first a box of chocolates ( or a love letter ) and on re-cast is an arrow.
W's passive would drop summoner spell orbs in the shape of hearts.
E would simply be her throwing a 'love potion' to an area, covering the area with heart shaped fumes. Walking into it makes a heartsplosion, with a dove circling around them for the time left before they're asleep. When they're asleep, it'll look like they've been charmed. Obviously with a few color changes because game clarity.
Her R would be her diving into a pile of roses and exiting a pile of tulips.
.
Even testing it in a custom game, Zoe cannot OHKO without these items, 3 Infernals, 3 Clouds, 2 Elders, Dark Harvest and Baron buff.
Dark Harvest must have at minimum 5 stacks.
Hitting the Q will do a little over 95% health, and Ludens will hit for around 4.8% health with Dark Harvest finishing the job.
Which technically means it's not a OHKO.
