I kind of like, though the the first two remind me more of push and pull. I had been playing with,

  : |<- push ;
  : |-> pull ;
  : <>  swap ;
  : ><  drop ;

Also, nice thing about your first two is that they translate well to Unicode symbols.

  : ◁ 
  : ▷

For drop, Unicode ⌫ makes some sense, though I find it a bit small.
