If Kerfoot is moved, I'd expect at least a Jarnkrok return out of him.
7th on the team in points behind the top 6 forwards and he plays a defensive role. The points have gone down, and if you bring in an offensively-oriented 3C you can probably live without him, but that would really be it.
Do you dump him because you want to bring more depth offense when you are mostly just deploying a bunch of solid 30-40 point defensive guys between him, Holmberg, Engvall, Jarnkrok, and Kampf and you need the cap over just dropping ZAR (who is clearly the weak point in the top 12 but also is cheap)?
If we are talking about pure expendability, then Holmberg and ZAR are easily the most expendable, but also make practically nothing. Between Engvall, Kerfoot, Jarnkrok, and Kampf, then Engvall is likely the next most expendable. He does PK, and he is good when he does PK, but he is 6th in ice time. Whoever you bring in can probably replace him on the PK, or you can give Holmberg/Nylander more PK opportunities since it would be the 3rd PK pairing anyways. Same with whatever he does on the PP... The PP forwards should be Jarnkrok, Bunting, new guy, and then either go 2 defensemen or use Holmberg (or Knies if he is in the lineup over ZAR).
