iirc Poppy spellvamps with the magic damage dealt Poppy lifesteals depending on how much ad she has since her Q does apply on-hit effects. This also means that her lifesteal only works with the ad portion that could possibly crit.

Pretty sure all you've stated is true, EpicMadness

If it is, then yes, they stack additively since lifesteal and spellvamp dont really interact.
