This is not always possible: 
  yp_kill/copy 3 items (i1 i2 i3)
  move to another point
  yank       (i3)
  yank_pop   (replaced with i2)
  move to another point
  yank       (i2)
  undo       ()  % nothing!
  
cycle round (becomes tedious with 15 items in killbuffer-ring)
  yank       (i2)
  yank_pop   (i1)
  yank_pop   (i3)  
  
but
  yank       (i2)
  yank_repop (i3)

That is an idea, however remember that some people have different
keybindings...

It should be easy to implement a killbuffer-ring with circle.sl from
jedmodes.sf.net.
