I think ideally yes. You might want to experiment starting with your feet a bit more parallel to the baseline and see if you can get your hips all the way from perpendicular to parallel to the baseline for maximum range.
I think for maximum power you need maximum distance from the ball before impact of all elements in the kinetic chain. So bending back in the trophy will help, maximum range of the hip will help, maximized upper arm path from trophy to vertical and shoulder high and the lower arm swing path from scratching the back all the way to impact and with pronation.
