While Donald X may not have thought about the trash being used, it's not about his intention, it's about whether it's possible within the scope of the game.
As an attack, I think it is doable. Actually Davio's first card works far superior to the one I proposed where the trashed cards are redistributed. I could see a politics issue here with trashing a card specifically for the next player, but there aren't many trashing cards that grant an extra action anyways to utilize this easily.
