I believe there is provision for that in org-link-protocols:

 ...
 ("man" org-man-open org-man-export)
 ...
 ("info" org-info-open nil)

The info entry has an org-info-open entry but the second entry
is nil. You can replace that with org-info-export and write the
org-info-export function to DTRT. You can use the org-man-export
function as a model.

Maybe you can submit a patch?
