I strongly doubt cachihua can do better, solus was unsundered, a king, militarily successful, high ranking member of a secret society, pretty decent at magic, tall, rich, pretty smart, sponsored the arts, fairly funny and pretty compost mentos for his age. I think you’d struggle to find a more eligible bachelor in all of hydaelyn, especially if his wife was already dead some nebulous period of time roughly 2-3 decades before ARR.

It does reraise the question of whether solus’ wife predated the bodyjacking, was part of some political manoeuvre, necessary for a dynastic crisis later down the road or a sentimental relationship that also proved to be particularly mortal like with his son.
