Hm... well you just gave your own idea that would work and get the point across.
Another possible way of going about it may be going with more of a "straight edge" type tattoo (be careful when googling pics of this as I noticed a few of them are kind of... bloody? :-/ ). I am not the most creative person either, but it sounds like you have a good handle on where you want to go with it which is more than some people that actually
get a tattoo go about it.
Best of luck,
