Would the Germans get their tank design almost dead right by 1939 if they adapted the infamous Christie suspension and grafted it onto the Panzer IV chassis? And instead of building separate tanks for separate roles, instead merely build a Christie Panzer IV that can be fitted with either a 50 mm L/60 or 75 mm L/24 cannon. The Christie Panzer IV would have up to 45 mm of frontal sloped armour like the Panther (although unlike the Panther it would be as mechanically solid and as easy to produce as the original Panzer IV). The Panzer Is would be melted down to make better AFVs. The Panzer IIs would mostly be converted into a mobile assault guns. Most Panzer IIIs would be converted into StuG IIIs, although the Panzer III in it's original form would make an excellent mobile observation and command vehicle. Do my Panzer ideas sound rum?
