You have been talking about two things: moving the point along visual
lines and the selection in visual line mode. The first thing can be done
correctly, the second is not supported. Of course you can rebind any
command to other keys and

  (define-key evil-motion-state-map "s" 'evil-next-visual-line)

does indeed work. However, there might be other commands in higher
priority keymaps, that's why you need at least

  (define-key evil-normal-state-map "s" nil)

This is sufficient in the default configuration and also works in visual
state because "s" is not bound (by default) in visual state. However,
some packages install bindings in visual state (e.g. evil-surround). You
can easily find out the currently installed bindings using C-h k <key>
or C-h b. (You can test a plain Emacs/Evil configuration by executing
`make emacs` in Evil's source directory).
