One way of achieving this with the existing scheme of things is:

  1. M-<
  2. C-x n n
  3. C-M-%
  4. M->
  6. C-x n w

Narrow from beginning of buffer (or a defun or wherever) to point, do
replacement and widen.

(I think) forward searches are more efficient than backward searches
through the buffer.

May I know what is your specific usage scenario?  Are you editing a text
file or a program source?  Why is that you want only backward
replacements and STRICTLY AVOID forward replacements.
