I've read about others using the 88-98 C/K seats because they are the thinnest bench seats and also recommended for Big and Tall.

I think if you use the short-bottom back seat from say an extra cab, you may miss having the thigh support.

You idea of using a smaller diameter wheel and a tilt column are good too. I've known of others cutting down the steering column. Here's a pic of a truck with one of hose seats.

This owner stated he was 6'3" 350lbs and that it came out of a 88 Chevy 1500.
