Just give in to it and get an estate, the squarer profile at the back really helps when putting cabs in the back. You don't even need that big of an estate to fit a pair of 4x10 cabs in in my experience.
Also estates will have a flat load bed rather than having to drop stuff in to a hatch back which again makes it way easier when loading stuff in and out, what size cabs are you taking around?
It's nice to have something with (nice and dark) factory tints in all the rear windows when your carrying around nice stuff as unless press your face right up against the glass you can't really see what's there.
