Looking at `org-babel-sh-evaluate', it should be enough to specify
:shebang, :cmdline, or :stdin header argument to force using script
rather than channel source block as input to bash:

#+begin_src shell :results output :cmdline bash
exec 0>&-
echo OK
#+end_src

#+RESULTS:
: OK


#+begin_src shell :results output :cmdline bash
echo 1
read -p "Next command? " NEXT_COMMAND
echo 2
echo 3
#+end_src

#+RESULTS:
: 1
: 2
: 3

I am wondering about the possible downsides of using script approach
instead of stdin redirection.
