Kayle isn't feast-or-famine at all (her passive, W and ult all let her be powerful independently of items), and if you check LolKing has pretty alright pick and win rates in Plat+. Her playstyle's a bit flat, but she's still doing well otherwise. Cass is meh right now because her numbers are too low, mainly because she's fresh from a rework.

I also don't think it's particularly good reasoning to assume that a concept is impossible to balance simply because it hasn't been done successfully before. Moreover, that's not really the kind of mentality you'd want to apply to game design, unless you want to constrict your video game and kill any potential for positive developments out of fear of messing up. Many similarly "impossible" concepts have been implemented successfully in League (e.g. double-edged abilities, light fighters), despite far worse failures ( and were melee carry prototypes, and among Riot's worst releases to date), and I think that unless there's a very clear-cut, hard-logic reason AP and DPS somehow can't mix, beyond semi-serious analyses of a snapshot of the game's state of balance, there's value in digging deeper into the matter.
