Done +++ An early A-4 Skyhawk in Aéronavale colors (@ p.2)

Nice work! Sure looks the part in Aeronavale colours! 

Now build another one, but with a Super Etendard's nose and cockpit section spliced on.  Exocet on the centre-line.
EDIT: On second thought... maybe don't. Quick mock-up in pixels reveals it would look silly. The Skyhawk's cockpit area is way taller than the SuE's, meaning a 1-to-1 splice would look somewhat hump-backed. However, giving a Skyhawk a finer, less wide nose and installing the SuE's radar and refuelling probe could look quite pleasing. Perhaps an Argentinian modification?

For a radar, there's actually not much to change. The RNZAF A-4Ks kept the original nose, but carried an APG-65 radar, so rhinoplasty would not really be necessary - unless you want a dramatic change.
But there's another Skyhawk on the list, a heavily modified "Super Skyhawk" as a rebuild of a kitbash I did when I was at school. Today, there are better means and tools available, though...

The Skyhawk looks great in those colours. Excellent build.
