I was too tempted to check if it is as simple as I hoped, I didn't test it thoroughly just created a map with different scales but that worked and as hopefully everything in the library is using HexConverter to convert between tile coordinates and world/cartesian coordinates if that works everything should work. Just replace your HexConverter.cs with this here: https://pastebin.com/eCr0kTJ4 There is a new static SetScale Method which you need to set once and then it might all just work.
