ATS 2014 AWD Staggered

Hey guys,

I was wondering if anyone or even if its even possible to configure the ATS 2014 AWD with a staggered configuration.
I am currently on 235/35/R19.

I want to keep my the front tires the same, but the back tires i'd like to have 255/30/R19 or a configuration that would work well with my front wheels.

Thanks !
