Could you catapult a magic stone?

I’m gonna multiclass sorcerer(for catapult) & warlock(for magic stone) and I’m just wondering if I could can then they’d need to make a dex save & by the rules it says if they fail it hits (cancelling out the need for a ranged spell attack for magic stone) I’m just wondering cause if so i could cast magic stone as a bonus action & embue 2 peddles catapult one & twinned spell catapult another dealing a total of 6d8 + 2d6+6 for only 2 1st level spell slots & 2 sorcerer points (also if I wanted to I could also hex them the turn before dealing another 2d6 & also making totem have disadvantage on said dex saves to not get pelted)

One of my other post clearly got some people mad (and for good reason) and just wanna know I’m not using any forbidden taboo combos
