The news has been reporting that PM Netanyahu (or someone on his behalf) offered (or floated the idea that) Aryeh Deri might be Prime Minister for an initial term of 1 year and only after that will Netanyahu serve as Prime Minister in a rotation agreement. (Deri says he is not interested, though I don't know why not)

Another proposal reported on is that of Netanyahu trying to sway Benny Gantz to join his coalition with Gantz's 8 mandates, in exchange for a rotation agreement, but this time Gantz would serve as Prime Minister first. Gantz supposedly said no, though I don't know why. I guess that ship has sailed.

Another idea discussed has been having someone else form the Likud, maybe Yariv Levin, serve as Prime Minister first, in order to form a coalition, and then after a year switch to Netanyahu.

Basically, Netanyahu seems willing to offer the position of Prime Minister, and first in a rotation arrangement, to almost anyone with a pulse other than Naftali Bennett.
