I have run GURPS, I consolidated the skill list to about 30 different skills. It just worked better from that point on. As I have done with every game I have played. Sorry, but as a GM I can only keep track of about 20 different skills, any more than that means the game breaks on me. I do not care about subtlety I want shit to happen, we will think about the rules later.
So you haven't actually used the BWr skill system in play, but you are assuming that it will cause problems? Is that correct?
I would encourage you to try the system as is. Once you've played with it a bit you'll see how the skills impact play. If you still don't like it where it's at then, by all means, change them. Just try it. You never know...maybe you'll like it.
