[CP] Heavy Tapper clone won't show up

[Brimbane]

Using Content Patcher (v1.27.2), I am trying to create a Heavy Tapper clone (called "Heavy Tapper (Upgrade)") which allows you to upgrade a Tapper. The idea is to make the new entry visible in the crafting menu once you buy the Heavy Tapper recipe on Ginger Island. Problem: It doesn't work, regardless what I am trying. Any input is appreciated.

content.json (abbreviated):

{
    "Format": "1.27.2",
    "ConfigSchema": {
  
[...]
      
        "Tapper Upgrade": {
            "AllowValues": "true, false",
            "Default": "false"
        },
      
[...]
    
    },
    "Changes": [
      
        //Crafting Menu and Language
        {
            "Action": "Load",
            "Target": "Data/CraftingRecipes",
            "FromFile": "assets/CraftingRecipes.json",
            "When": {
                      "Text": "English",
                      "Tidy Menu": "Small First",
            },
        },
[...]

    // Tapper Upgrade
    {
        "Action": "EditData",
        "Target": "Data/CraftingRecipes",
        "When": {
                  "Tapper Upgrade": "false",
                "Tidy Menu": "Small First, Big First"
            },
        "Entries": { "Heavy Tapper (Upgrade)": null }
        },
[...]
          
    ]
}

CraftingRecipes.json (abbreviated):

{
[...]
        "Tapper": "388 40 334 2/Home/105/true/Foraging 3",
        "Heavy Tapper (Upgrade)": "105 1 709 10 910 1/Home/264/true/null",
        "Heavy Tapper": "709 30 910 1/Home/264/true/null",
[...]
}

It would have been at least nice to know if this is possible at all. Apparently things don't work the same way if you have to buy a recipe as a prerequisite for unlocking a crafting entry.
