First off a big spoiler for you but Daryl is going to be in the comics.
Your whole comparison rests on the relationship with Carol and that was only one aspect of Tyrese's character. A relationship that honestly is not nearly as close as what Tyrese and Carol had and then lost in the comics.
Please explain how they are basically the same character with just different backgrounds? I already hashed out how they're different in a bunch of ways. Yeah the show isn't going to do the same things as the comic but all you're banking this comparison on is Carol. Take her out and how are the two the same in any way? They're so different. Tyrese was dealing with his daughter and her bf and then her death. He then killed the bf for killing his daughter. Throughout he was good friends with Rick and was basically 2nd in command shortly after he joined the group. Then they had a falling out over what Tyrese did and got cool again (months later) but not to the same point they were originally and then he died.
Daryl started off as Merl's yes man and a racist and evolved in to a loner hunter and tracker that collects walker ears and then became pretty obsessed/fixated on finding Sophia while going through his big brother issues and then to a lesser extent his loner issues with Carol.
I mean if anything before Shane went complete crazy and reckless a lot of elements in his character on the show are closer to Tyrese than they are Daryl's.
I'd go father to ask why you think Tyrese won't be in the show?
If you think Daryl and Carol are gonna have a relationship in S3 that's just nasty
