My key fob Is a brittle Pos lol wondering if it's possible to use a newer style caddy or chevy key fob on my 05 tahoe? I hate the old style so much.

Hmm I am not sure if you could or not, you could try to sync it to the truck. Biggest thing that might happen is it would not sync. There are instructions on how to get the truck to learn new fobs. I know when I bought my 04 I didn't get fobs with it and bought two new ones. The old style and was able to program them on my own. Save money that way, no dealership fees.
