Too much flex, IMO. The diameter is with the wrap, so the actual core is considerably thinner. The whole reason for the core + wrap construction is to give them flexibility, which is exactly what you don't want. With each shot, that thing would be twanging like ... a guitar string.For the front sight elevation, I was thinking of cutting a bit off my low E guitar string to add some height, and then just support it by gluing it, then support wrapping with electrical tape. The low E is .046 inches in diameter, the A is 0.036 inches, and D is 0.026 inches. Plus, the strings are nickelplated steel wrap wound around a hex core so it should be plenty stiff and durable. You think it could work?
