Has anyone put the single cab bench seat in the front of a dual cab legally?? The reason is for the growing family

I really want to keep the hilux if I can... and there aren't many option for a 6/7 seater ute unless you get a iveco daily 4x4 or something similar... I know that there appears to be a six seater hilux in the 4x4 but it the 2012 or around there??(not even sure if it was released in Aus)
Thanks guys
