Without opening cheatmenu... heck, even using it how hard is it to woo a Perisnoan faction ruler into marrying you if there is even a remote chance of pulling it of?
Eliminating the whole line of succession/ family tree?
Shaming the spouse into an untimely demise?
Be a walking god/goddess among men to (hopefully) make the ruler do your bidding with some blackmailing?
I really can't find a legitimate non-shady way of doing so, and even IRL books referencing circumstances of nobles remarrying are pretty sketchy, like there is always an angle for both parties.
