DIY LED Placement Feedback?

[Enigma]

I'm working on Martin's BC29 kit. Originally this was going to go on an NC12 (Nanocube 12), but (providing the new tank doesn't fail its leak test) it is now going on an NC24 (for livestock sustainability reasons).



The top of the heatsink in the photo will go towards the back of the tank, and the bottom will be at the front of the tank.

With two drivers, I can use a maximum of 14 LED boards. I do have an extra red board that I can swap out for something else.

In the right and left columns, I have (from top to bottom):
Royal Blue (RB)
Cool White (CW)
RB
CW
RB

In the middle column, I have (from top to bottom)
Blue (B)
CW
Red (R)
B

The royal blue boards and the red board will be on the same driver. The cool white boards and the blue boards will be on the same driver. That will change if I swap out something for the extra red board, however.

Feedback (before I epoxy these things in place) would be most excellent.
