That's what I was thinking as well. My only worry is how to re-make a wrench into a straight driver. Don't want to buy a Dremel just for that.
In my research I found that Wenger used a flat phillips on some of their models, in the same layer as the blade. If I could get a hold of one, I could even reduce the thickness by one layer. That is if the flat phillips works well on both slotted and phillips screws.
I also would like to replace the fat Evo scales with something thin.
