Could it be possible to answer a new research question with the help of literature review? Could this be published at a symposium?
Actually, for most things you need a literature review, since you need to know what has been done already. But if the complete answer shows up in the review then there is nothing left to research there and you need to move on.
I hope you have an advisor somewhere, or access to some sort of academic guide. You seem to be unsure about how to handle things, and a guide can help get you on the right track.
And doing a good literature review can also help teach you common techniques that you will need to answer your question.
