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.)
