A dead ruler is a dead ruler, sorry to say.
Also the consort exists for only one reason: to make dwarf babies. Consorts aren't actually royals, I think, even in real life.
In which case, instead of "Consort demands <level foo> Bedroom; <level bar> Dining Room; <level baz> Tomb", surely it should be "Noble demands <level ni!> Office; <level foo> Bedroom; <level bar> Dining Room; <level baz> Tomb, and <level foo> Bedroom; <level bar> Dining Room; <level baz> Tomb for my partner".
At the moment the consorts get unhappy about "lesser" dwafs getting too good a room, and seem to expect more or less the same rooms (all but the office) as their SO, at least for the married nobles I habitually cater for. (Too lazy to check Wiki to ensure this is completely correct!) And they get upset about other people's stations being over-catered for, so they must have at least some pretentions.
Not a totally serious suggestion, save that a demand of "my husband will have an armour stand in his bedroom", or even "I command you put a coffin in <random dwarfs> room" (as a present or a subtle warning? who knows...) might be interesting.
Of course, a consort could have their own self-esteem non-issues (after all, nobles marry nobles, IRL), but every now and then you'd get a Mrs Simpson to your Urist McEdward, without the resulting abdication.
(Actually, have abdications been mentioned? Or is 14thC politics a little too absent of "retire to [the|another] country potential in a "Noble 'til I die!" manner.)
Abdications? In DF? If abdication is another word for "spike trap", then yes.
You'd think the nobles would eventually realize that they have the highest turnover rate in any fort in any region ever. Typically the only "nobles" I have that survive are the appointed ones, because they're actually useful.
It would be cool if once a noble is dead, his/her corresponding consort would lose his/her profession and become a peasant/whatever their highest skill is.
So here's the questioney bit: does the king consort not take over the role of king? does the queen get replaced like my hammerers do? (where do they all COME from?)
The first hammerers were born when Armok's bloody beard hair shed onto the ground.
