My thought: I wouldn't do it. Each knife and design has it's strengths and weaknesses. Your knife looks like a scandi grind - very popular with hard use bushcraft type knives. One of the advantages is ease of free hand sharpening. If you commit to a secondary bevel, it will be thick behind the edge, and over time will only get thicker. If you stick to the scandi grind the thickness behind the edge will not increase and you'll still have the advantage of the scandi grind. If you do commit to a second bevel you will have to remove a lot of steel to get back to a scandi if you ever change your mind. I'd just use your enzo for carving.
