I can't think of a way offhand to do that, but you can map a character
to apply the filter at the end of each line.  For example:

  map! ^X^M ^[!!tr A-Z a-z^Mo

Note that those need to be literal control characters (see attached).

In this trivial example, I've mapped ^X-RET to exit insert mode,
filter the line through tr to down case the letters, then open a new
line.  So if you were to source the attached file, then enter the
sequence:

  ABC
  DEF

and end each line with ^X-RET (rather than just RET), then the buffer
will contain

  abc
  def

and you should see each line changing case as you move to the next line.

Note (and a question for Tom), for some reason this doesn't work quite
as I would expect when the cursor is on the first line of the window:
the new line is scrolled off the top of the window as opposed to just
hitting RET, which leaves the new line as the first line of the window
and advances the cursor.
