Could you form a medley relay using only blood relatives?

Three older brothers and I, ages 62, 60, 59, and 55. All four of us swam in high school, and three of us swam in college. I (55) would swim backstroke, 59 would swim breaststroke (missed the '72 Olympic Trials by 0.5 seconds in the 200 ***), 60 would swim butterfly ('70 high school All-America in the freestyle relay), and 62 would swim freestyle. We talked about doing this years ago, but never got around to setting it up. I'm the only one who's currently swimming (and not very swiftly), but maybe we'll make this happen someday.
