I believe this should be possible using a bit of Elisp:

,----
| (org-add-link-type "att" 'org-attach-open-link)
|
| (defun org-attach-open-link (file &optional in-emacs)
|   (org-open-file (expand-file-name file (org-attach-dir t)) in-emacs))
`----

Put that in your init file, or wherever you place your customizations.
 You can read more about adding new hyperlink types in the manual.[1]
By the way, the function is only passed a single argument (the text of
the link); ‘in-emacs’ will always be ‘nil’, unless you’re also calling
it programmatically elsewhere.
