Yes, but eshell has some disadvantages.  The error messages aren't very
clear.  That's a problem for me because I make a lot of mistakes using
the shell. Also, I sometimes use MS Windows where it's useful to have
M-x shell go to the Windows shell (cmd.exe).  Some other people may want
to do it because they use a different shell and eshell mostly immitates
bash.

Looking at the code a bit more I think it's best to do it this way:
* Rebind RET to a new function (only in shell mode, not in comint).
* In the new function filter out all the special commands & deal with
them.
* In the new function pass through everything else to comint-send-input.

BR,
