Don't get timbre and range mixed up. I hear a lot of singers with deep voices hit notes above C5 with a lot of power (Michael McDonald, Tom Jones - and they are not country.) Most people can sing higher than they realize. But in most cases they pull and squeeze and are never able to reach those high notes. Or they think they will only be able to sing those notes in a falsetto sort of way. Just saying, find a good teacher, and be patient. There may be people you know that sound good without lessons, but they are probably using their voices more correctly by default. If you train with a good teacher, you will find the sound you are looking for.
I personally wasted years thinking I'd get there if I just continued to practice in my own way (incorrectly.) Then I bought audio programs, and thought I was doing things correctly, but I still wasn't. Then I started training with teachers and that made the biggest difference.
