I will accept Topher as Eddie if he is a cliff hanger at the end of SM3. Eddie Brock in his early reporting years had a physique much like that of Topher. He had light brown/blonde hair and was tall and thin. However, once his hate for Spider-Man came about, he began lifting weights and buffed up. If they show him begin to hate Spidey towards the middle/end and have him buffed up and bigger for SM4, then Venom could deffinately work.
