Spearhead to DS2 or DSII Divisional

I've just got "Spearhead" by Arty Conliffe. It's WW2 Division Level wargaming,
where each model vehicle or infantry team on the table represents one platoon
of the vehicle or one platoon or company of infantry, The scale is 1" = 100
meters. After reading through most of it, I thought that it would be an ideal
basis for converting DS2 so that really big games could be played.
