a stretch 4 doesn't really give you that much of an advantage; and the down-side of moving your "Rebounder" outside that far is that you sacrifice your offensive rebounding ability.
What we need is guys like Seljaas who can actually hit the 3-pointer reliably; this takes the defensive pressure off of your big men inside and lets them operate.
I don't want Childs shooting 3 pointers; I want him crashing the boards; leave the long range jump shooting to your 1-3 positions.
