The thing is, if you did that, you'd break all the plugins that rely
on the current behavior. So that's out.
However, I think you could write your own command to do that. Name
it whatever you want, but of course it must begin with an upper-case
letter. If you want the :s command to invoke your command, you can
use the :cabbrev command to replace :s with your command, something
like this (adapted from my vimrc but otherwise untested):
cabbrev <expr> s ((getcmdtype() == ':' && getcmdpos() <= 2) ? 'MyS' : 's')
The details are left as an exercise for the reader, as I long ago
just got used to typing \r instead of \n in the replacement string.
