Licensing question for fork in modpack

[asanetargoss]

Hey there! I'm the developer of Hardcore Alchemy: Magic With Consequences, a MultiMC-based modpack for Minecraft 1.10.2. As part of Modpack development, I forked your branch of Ars Magica 2:

https://github.com/asanetargoss/ArsMagica2

With Curseforge support for Linux seeming likely, I have been exploring the possibility of uploading HcA to Curseforge, but doing so would require the changes I have made to the mod to be on Curseforge in some fashion. With that in mind, I have the following questions:

• What is your preference: Integrating the changes upstream, or a fork with its own Curseforge page?
• If a fork with its own Curseforge page, what is an appropriate revenue split?
