From the Wings of Liberty to the LOTV prologue missions, he has, I think 7 missions in total, which is almost as many as Novas.
Someone could even do this in custom I think but it would be way cooler on the official menu, since its missions by Blizzard and focused on Zera. Btw all these missions are F2P so no problem there.
Just grab all cinematics related and all menus and all missions and make it a "mini campaign". Think it would be cool
