I did the same thing with my set- Item cards are kinda rare in the game, and nobody could ever accuse betrayal of being a 'balanced' game to begin with, so I don't imagine it matters too much.
I also keep the eight or so haunts eliminated from the first game as 'alternates' to use if we wind up facing something we already did.
