I'm not against a try with a Panzer II, as it's usually worth trying something but I feel it might not turn out too well. I like the disadvantage as German, you often have to sneak to enemy flags without being seen by the vickers tank or/and always have someone with an AT rifle with you that can definitely deal with a vickers tank, as the Vickers "tank" is one of those vehicles you can fight pretty well with an AT rifle anyway.
Imo Panzer II, which can destroy vickers tanks easily is not a good option and does not fit the whole paratrooper operation too well either in my opinion. Vickers tanks would have to hide instead of swarming out to find paras in the countryside. Generally the Panzer II would prevent pretty much any attacking move from the brits in the area it is around and personally, I like the current gameplay on this map, as this invulnerable threat (in this case the Panzer II) is missing and a lot of the battle is fought with a lot of movement in trucks or Bren carriers all over the map. Add a vehicle that can deal with anything and is only slightly vulnerable (if positioned properly nearly invulnerable) and you'll have a way more static game.
Feel free to try of course, but I think it will not be that nice, as it will simply stay out of 2 pounders range on one of the multiple hills, not allowing anything enemy to do an attack move in it's area.
