Saturday's 3-1 defeat at MK Dons saw Kiwomya's men equal the worst ever start to a league campaign in the clubs' 151-year history. Left-back Alan Sheehan (hamstring) and forward Danny Haynes returned from injury to start in Milton Keynes.
It remains to be seen if they will keep their places but Kiwomya might stick with Marcus Haber up front while fellow new signing Jack Grealish could be handed his full debut after making his first appearance for the Magpies from the bench at the weekend.
Kiwomya, who is still without defender Haydn Hollis due to a knee injury, said: "Some players are just not doing enough to warrant a starting place. There willl be some changes, most definitely."
