As ABX suggested, iso-wotsits are certainly one way to go, but may be slow.

Your original idea of a CSG of torii and sphere looks like the right way to go.
For example,

#declare myTorus = torus{1, 0.5}

difference{
  sphere{0,1.25}
  #declare YRot = 0;
  #while(YRot < 180)
    object{myTorus rotate z*90 scale<1,1.5,1> rotate y*YRot translate y*1}
    #declare YRot = YRot + 15;
  #end

  pigment{Yellow}
}

shows possibilities....
