Could you change the picture and name of your mod. If this is really intended to be a private mod for your private server you have made it such that it shows up in searches and predominantly looks like the true mod. I am getting bug reports from people thinking they are installing the correct mod but it doesn't work because yours is very far behind.

Beyond that, the proper way to adjust the recipe in someone else's mod is not to copy and publish something with a trivial change, but to create a dependent mod that adjusts the recipe.
