Yep, they're a good couple. :3 Or they vacation to the US, I bet Botan would love that.

They'd have pretty flowers everywhere and a stunning Christmas tree of Kurama's own design or something, like with a pine tree having real flowers on it or something. Botan would bring everyone eggnog and tea and they'd sin songs because they're a cheesy sort of family who then goes out and has a snowball fight on Christmas Eve.
