Not without some dirty hack.
`shell' is based on comint.el that uses a buffer local history variable
(`comint-input-ring') for every buffer.
However, you can try to copy the history from one buffer to the other:
(defun my-use-comint-input-ring-from-buffer (buffer)
(interactive "b")
(setq comint-input-ring
(with-current-buffer buffer comint-input-ring)))
If you do that from shell2 to use the history from shell1, they share
the same structure as history. That works because the history is
realized as a list, and what you copy is internally a reference to that
same object.
Dunno whether doing that can cause any problems, but it seems to work
here as you want.
Michael.
