I would recommend you read Mays 'Strange Victory' It is probablly the clearest English language account of the development of the Sickle Cut operation. Some of your ideas about Halder & other details are at odds with the record. For the rest of it I'd recommend some solid historians like Doughty 'The Breaking Point', Jackson 'The Fall of France', Loyd Clarks 'Blitzkrieg', or Hornes 'To Lose a Battle' and Chap,ams 'Why France Fell' which have stood the test of time.
Those should give you a better base for this.
