Could you do something with the sword one? I really like that idea, but with some tweaking. I'm not at my own PC so only have access to MS paint.
I'm thinking of making the sword smaller so the blade stops where the sheild does, and extending the top around the hilt (which I reduced in size). Maybe make the blade narrower, or fudge the flag's cross thickness so that it's on top of the cross rather than blotting it out entirely.
It's hard to describe, but I was going for one of those "ribbon/tape" style upper borders, and was thinking of having "THE FINAL BATTLE" on that instead of across the flag's cross. You need to have a background behind the sword hilt. Maybe some element of the eagle from the other ideas you had, or maybe something with the German iron cross?
