Xander has a house full of slayers next door to an elderly doctor named Hawkeye Pierce

I'm looking for a story where Xander is "house mother" to a bunch of slayers.  They become friends with an elderly man next door who turns out to be a doctor.  Dr. Pierce tells them to call him Hawkeye (as in M*A*S*H).  At one point Radar comes for a visit, and also the ghost of Hawkeye's (I think) late wife, Margaret Houlihan.  Doc helps them when a slayer gets pregnant, and when a slayer is fatally wounded in battle.
