Of the three two Glick & Liberman are in the Kenesset, Yaalon resigned both from the DM and the Kenesset so I don’t think he is coming back unless there is a new election.
Glick would be more sympathetic to Haradi needs. As far as drafting Haradis into the army while Liberman has already said he wants to and will have authority as Defense Minister, Agiudah has already said it would leave the government if there is a change in status quo, if Shas leaves also new elections are needed.
While Yaalon has experience as Chief of Staff, I think he will be found next time in Labor or with Lapid.
