I have look it up, You have to be the creator of the project. Don't use music, images, video, or other content that you don't have the rights to. Using copyrighted material is almost always against the law and can lead to expensive lawsuits down the road.

So no you couldn't use a graal server as a kick starter project because you do not own the content. If unximad post say get graal on ps4 then he could since he owns graal but that's about it.
I hope this has answer your question
