Honestly, you need a series of very capable women ruling somewhere (perhaps in Britain? Less external danger), followed by what is a line that keeps giving birth to girls rather than boys. There is an advantage there to succession via matralenial marriage. Every generation, a different noble family can marry in, and lands get added to the crown.
It could be an effective way to accidentally strengthen the monarchy.
A PoD could be a marriage of a King to a Basque woman, ideally a Navarranese Princess, who proposes the solution when there are no sons, simply to change the law, or even convinces her husband to allow it, and marry their daughters off matralinearly.
Another way it could be used is that talented men could be married to daughters, given lands, and have those lands return to the crown.
The larger nobles would catch on of course, but lesser or middle-ranked nobles may still be game. A lifetime of royal power, and favours for the family, in exchange for an inheritance? Not a bad deal.
What could be an interesting side effect (if Maria Theresa is anything to go by), is a better run state, but also a more aggressive England. If the King-Consort leads the armies, and the Queen runs the state, it can run better, and the Queen has an incentive to over-compensate. Cue earlier diplomatic and military moves. (Perhaps an earlier conquest of Ireland? Or for the sake of proving she can, Iceland and others - I doubt France is as likely a goal for a female ruler - trying to bring France and Britain under her rule might be hard).
At the same time, if deployed well, other feudal states can be undercut - marrying the Duke of Burgundy for example? Suddenly England and Burgundy would be under the same Royal couple.
