I can see it working, but only if a certain subset of both parties make up the overwhelming majority of that party's seats. The old "wet" liberals, who have mostly disappeared from federal politics thanks to the teals and the 2022 Greens, and Greens who might be hangovers who joined the party a while ago but are more of a natural fit with the teals.
You're certainly not going to get a coalition between a Dutton style Liberal Party and a Sriranganathan Greens.
