Hey Jenk,
That’s a great idea for a Poor Man’s AA50. There is a AA50 map IL made that you can use, it’s a matter of printing it out.

Depending on how you want the board to look, it can be cheap or expensive (color printer vs. professional print work).
You could use the battleship from AA Classic as either the cruiser or battleship, also probably use the pale color as Italy so it stands out. As for China, you can use the Chinese inf from AAP if you have it.
I am not sure about using the AAR map as there are many differences like Ger does not border Italy, Switzerland blocks direct access.
Good luck
