I am doing a 2 ch 400w/4ohm dual differential bridged amp and it just hit me that there may be placement considerations on where in the enclosure to put them. My instinct and current plan is to put them as close as possible to each other and in as much of a symmetrical way I can, like shown in the picture.
Now looking at it I started thinking if this might be problematic with supply currents creating magnetic fields inducing more distorsion vs separating the amp boards and getting different cable routing and lengths.
Any experience, thoughts on this?

Whatever it takes to keep the inductance of high current paths down, really. Good board layouts tend to be running V+ and V- right next to each other along the heatsink, for example - the supplies with their current spikes being drawn certainly are among the most critical elements, but the Zobels are fairly critical as well.
