I think from what I can see there are four potential gaps:
anything post-Paris and pre-Bangkok can potentially be used as a “bread and butter” Hitman scenario
Anything pre-Mumbai can be used for eliminating Shadow Client connections
A small gap between Haven and Dubai
Potential gaps between Dartmoor-Mendoza, either 47 trying to get to Berlin, 47 and Olivia trying to evade the ICA or 47 dealing with Providence assets between Chongqing and Mendoza trying to find Diana
I think the cut Johannesburg mission could easily be put into one of these gaps, especially if it’s pre-Hitman 2
Would be unconventional, but since we already have cutscenes from Lucas Grey’s perspective, why not imagine missions where we play him during the time he led the militia against Providence?
Johannesburg, where they attacked the Ether corporation, or Thomas Cross’ kidnapping would be possible missions.
They could make a whole campaign out of Lucas Grey’s involvement in stuff! Having the intro mission be a tiny thing where you eliminate Cobb, then moving on to the main event in Johannesburg so there’s finally a second African map in the trilogy! They could also do new missions with new areas on Dubai and Dartmoor showing what Lucas Grey was up to while 47 was dealing with the partners
Grey’s characteristic feels more action-oriented to me. I’m not sure implementing this to the Game would be a good idea. This might work as a standalone spin off game tho
Know what this reminds me of? Anyone ever played Shadow of Mordor? In that there’s a DLC which adds a new map to explore, the DLC’s story has you play a new character in this map but they also added this map as a place you can go in the main game
I imagine a Lucas Grey campaign could be similar, where the campaign versions are Lucas Grey and then you can also choose to play a 47-ified non-canon version with starting locations and such. Bit like the Herbalist ET vs its assignment
Maybe not enough there for a whole game. A game within a game though? Like a DLC inside WOA where you get 3 Lucas Grey missions and it’s known from the start they are more action orientated could work, but then again maybe not.
We want so badly for there to be more, but really if there is more and it’s not 47 in a sandbox per usual we will not like it.
Maybe after China make us revisit the ICA facility in Greenland during an Interpol raid where there is also extensive, snowy exterior where it heavily snows. (opposite-style viewcone distance of Haven)
Plot could be to destroy analogue left-over evidence of Diana and 47 after all digital data of them got deleted before the leak.
Retrieve or destroy any evidence of 47 in the facility before the raid team gets to it! Maybe even eliminate some person who works for ICA there who you suspect will talk ?
You could even have the yacht and airfield be part of the mission, remixed a bit or in the process of being destroyed. And you walk backstage between the training areas as well.
