Training for a Copperhead

[apps567]

I am a relative intermediate in reptile care as I have a leopard gecko, a bearded dragon, and a corn snake. Now, somewhere very long down the road, I want to get a copperhead, no other venomous snakes. Copperheads are just so beautiful. Since I have no previous experience with aggresive snakes, I was thinking about keeping a similarly sizedsnake with a similar temperament for a few years or so. I was thinking of keeping a banded water snake and wearing no gloves or anything as motivation to not get bit and as training for the copperhead. Do you guys think this is a good idea and, if after keeping a banded water snake and not getting bit at all, I would be ready for a copperhead? I heard they were rather sluggish but when handling them I will still be extremely alert dont worry.
