In a word, yes, it will look tacky. There is no other trim like that on the car and it wouldn't even flow with the trim that immediately follows it onto the 1/4 panel. I don't even like chrome door handles on these cars. Just remember that there isn't much that hasn't been done to these cars over the years so if there is an idea that has no real precedence, it probably isn't a great one. That being said, it's your car so if you like it then go for it, but it is less work and probably cheaper to scuff and re-paint them back to the original satin black.
