I would replace the Panzer II with Panzer IV. It was a workhorse that was constantly upgraded and in service the whole war. Panzer II was a light tank that was only used for the first couple years.

I would replaice the Type 59 with the Abrams.

I saw a Panzer IV at the AAF Tank Museum.

It had seen action in the 1967 Six Day War.

Still looked like it could go a few more rounds, as well. It was a well-designed machine.

In short, long enough to establish the concept of blitzkrieg. The PzII was used as the main tank in Poland and France. That is one of the ultimate game-changers in the history of warfare.
