Both Corsairs and Harlies have far too few options to really be their own list. I could see a Corsairs/Harlies/Ynnari book, but they'd have to be usable with
CWE or
DE books.
...Since when? The Mymeara list had 22 different unit entries in it (Prince, Voidseer, Baron, Reavers, Ghostwalkers, Cloud Dancers, Falcon, Venom, Voidstorm, Malevolents, Wasps, Hornets, Vypers, Nightwings, Phoenix, Balestrike, Warp Hunter, Firestorm, Fire Prism, Night Spinner, Lynx, and Vampire); and the way 8e organizes datasheets there could be as many as 11 more from splitting off jetbike versions of characters and jetpack versions of both characters and squads.
If the Corsairs have too few units to be a Codex then you should be taking a good hard look at the Custodes, Grey Knights, Imperial Knights, AdMech...
