Very nice story. Kind of reminds me of AMG's Scenes from a Life fic. 
And then there's this....

but from everything I heard about Konatsu and Ukyou it seems unlikely that >they'll get married.

Oh really? Think about it, who else is she going to marry?
Ranma? He has his heart set on Akane.
Ryoga? His affection is split between Akane and Akari with Akari gaining ground.
Tsubasa? She has already stated she doesn't want him.
Some other fanfic character? Make him yourself, but he better be probable.

Not much other choice is there. Besides, give her a few years and things might change between them.
