Sure. Just distinguish the two methodologies and provide a clear explanation why you are mixing methods. Imho, it would be a good means towards triangulating your data and could provide a much richer analysis. One thing to consider: if this is for a thesis or book, go for it. If this is for a journal article, I'd break it up into separate papers.

The book chapter at the following link summaries these 2 and 3 other qualitative methods. You may find it helpful. It is from Creswell's book

Not every phenomenological research is narrative and not every narrative analysis is phenomenological. But it is possible to combine both approaches. You have to be explicit of the why and how of your combination.

It depends on what type of phenomenology you are using. For most forms of phenomenology, narrative can be a good match. This is especially true if you are a narrative phenomenon. For example, I have used hermeneutic phenomenology to study stories about emotional experiences in the workplace. Mixing phenomenology and narrative makes sense in that type of study. Be careful that you justify your design choice. 

I think you would also need to have a clear rationale as to why these 2 methodologies are being used together.  As mentioned, phenomenology is generally about capturing the experiences of a group, or perhaps a single individual. Narrative methods are aimed at capturing meaning-making as heard through stories, but each person's narrative and set of stories can, and often should, stand alone. There might be some meta-narratives present, but each person's stories are important in their own right. How you present these data, distilled themes vs. storied narratives, is key. If you do pursue this approach, consider using crystalization (L. Ellingson, 2009) as a way to present data in multiple ways. I do this with my narrative work as well, and it can be very powerful.
