trait UnionType[Types <: \/[_, _]] extends Default

This allows to restrict the handling of family to only some subtypes (not required to be sealed in this case).

import reactivemongo.api.bson.{
  BSONDocumentWriter, Macros, MacroOptions
}, MacroOptions.\/

trait Family
case class TypeA(n: Int) extends Family
case class TypeB(s: String) extends Family
case class TypeC(f: Float) extends Family

val writer: BSONDocumentWriter[Family] = {
  implicit val a = Macros.writer[TypeA]
  implicit val b = Macros.writer[TypeB]

  Macros.using[MacroOptions.UnionType[TypeA \/ TypeB]].writer[Family]
}
