In regards to the rituals that Goetic magic uses, probably not. At least, not the way they are published. Since they center around the Christ figure and the Abrahamic god the rituals probably would not work for you, quite possibly leaving you in a bad position if anything did show up. Now, you could probably take the rituals and modify them to your belief system. I would first spend a great deal of time actually learning what the ritual is intended to do and why, and then modify it.
The other consideration is that there are basically two types of entities in Goetic magic: ones that were worshiped by other cultures and "demonized" by Christian magicians, and ones that originate from Christianity itself. You would want to do some research. Those that originate from Christianity itself probably wouldn't be good to work with. They probably would not respond well to your modified rituals. Those that were from other origins would respond best to rituals invoking forces from their origin. You would, of course, have to judge whether that is right for you or not.
Obviously, this all assumes that you are familiar with the basic workings of magic and ritual practice. Working with Goetic entities (contrary to all of the post sure to follow telling you otherwise) is not for beginners. Don't jump in to too much too quick. The psyche you save may be your own.
As always, just my advice.
