"Mega Haunting Guise" already exists in the form of Liandry's Torment. Problem is, the item fits tanky champions rather than glass cannon nukers.

Void Staff tweak could open up a possibility of alternative HG upgrade, but keep in mind that every midgame item, even is designed for "oldschool mages" such as Xerath or Cassiopeia, can just easily get abused by "mainstream" mages such as, or. Mages already dominate midgame.
