Spacing COB's for 2x3 floor space

2x3 footprint, think there is 4' from growing media top to bottom of light.
I've been playing around with shapes on the tile floor to figure out how to spread the following:
Main source of light is 4 x Vero 29's at 1050mA.
I have one blurple COB, probably running at about 22W in the middle.
I would like to add 2 x luxeon 12w blue and spread 10 red (~2-3W ) around the top.

Do all the COB's all in a straight line down the middle - or 2x2 with blurple and blue in the middle? Almost straight down middle with slight alternating offset?
