You mention emacs shell mode.  But if you want bash to handle the
completion then I think maybe you want emacs term mode with bash.
Using term mode is different from using shell mode.  But you get
exactly the bash features you wish.

  M-x term

Note that most C-x keys are remapped to C-c inside that buffer.

Keys are mapped:

The buffer is allocated a separate tty.  The result is that most keys
are passed through directly to bash and therefore all bash completion
works from bash without emacs in between.
