crossoverfic | a question and a challenge

I've been wondering if such a crossover animal exists and if so where I might find it.
The challenge in question is for a fic that takes Jadzia 'Old Man" Dax from ST: Deep Space Nine and Bill "Old Man" Adama from Battlestar Galactica and has them meet up.

As stated earlier if such a crossover exists between the two shows, great! Even if it does not
have these two characters featured in it.

I don't know enough about Battlestar Galactica to do it myself, however, it is a crossover that I would very much love to see happen.

Thanks and take care, karrenia
