Can I use other mods as masters in my mod

[Thasic]

I am working on a sort of patch between two mods I use that compliment each other. I am having problems contacting the mod authors. I will not be using any content from either of their mods, I'll just need to use them as masters for the patch. With that being the case, do I need permission from the authors before uploading my patch. I intend to give all due credit to the two authors, even if they are not active on Nexus. I just don't want to break any rules with my first Skyrim mod.

If you're going to upload it, you need permission.
