In contracts I think it could be possible to make your own Elusive Target. Here me out.
Select from any of the Elusive targets roster
Walk a route you want your target to take (accompanied by bodyguard) with no ability to raise alarm, harm anyone, climb or act in a way a target can’t
Then you’d have to complete your contract as Agent 47 with a Silent Assassin rating to upload
and the biggest change to the usual contracts is that it can only be attempted once (I’m saying the standard Elusive Target rules)
