my question more less is could the high gear be changed to a 1:1.5 (form a 1:1) reason is fairly obvious with 3.55 gears that would put me in range for 33 inch tires, but if I'm not mistaken it's just straight shaft?

I plan at some point to install a 6 planetary gear set, and a wide chain kit from dodge and s10 231's to strengthen the case, so if it is possible that should not be a problem,
