Do you really think that politicians such as Grieve are going to stop their cross party cooperation just because an all woman cabinet has been mooted?
This is just one potential strand.
We are in an unprecedented situation where party politics is collapsing. We potentially have conservatives willing to vote for their own government to fall leaving 14 days for a new administration to form.
In that case labour will attempt to form a minority government with a leader who seems quite happy to brexit, we have some sort of national unity government (unlikely to be supported by corbyn) or we have general election.
I think if Grieve is willing to vote against his own party and sacrifice his own political career for what he sees as the good of the country a potential all female unity cabinet is not going to stop him.
In fact if this female unity cabinet is formed with the sole intention to stop brexit and legislate for another referendum I think Grieve would embrace that option. Him and Starmer would probably have a draft bill ready to present to the cabinet. (He'd probably also be made head of one of the committees dealing with this)
We already have a government that no one has voted for but don't worry we're not going to get an all female unity cabinet.
This is a political strategy by Lucas, nothing more, to apply pressure to labour who refuse to consider any option other than Corbyn as PM.
It's not going to work but I tell you if this group of women give any indication of interest it would send an earthquake through the system and possibly force labour to reconsider their strategy.
