Antioch character - Trench Priest?

Evening folks,

I smooshed together this character today, using a Perry miniatures foot knight body, and some Sister of battle bits. I was thinking it might work as a Trench Priest, but I went with a cloak on her back to try and tie in with the hooded head, and this sort of leaves me no space to do the whole 'big cross tied to back' thing.

Maybe I could model the trench shrine on the base somewhere? Or she could simply be a shrineless priest? I'm unsure, let me know what you think. Open to any other suggestions and additions too before I commit to priming!
