Hi Porshe!
I would probably put the conflict star hexagram above the door. That way you've cured the entire room. If in doubt, muscle test just to make sure.
When I've used more than one hexagram in an area, it generally seems best to put them at least six feet apart. Otherwise it's like having two bar codes on a piece of produce. The Universe doesn't know which one to go with. Again, muscle testing (or dowsing) are great ways to doublecheck and see what is energetically best for your specific circumstance.
All the best!
