I think some white is needed for growth too during flowering, but just not as much. And what you are saying is making sense as far as lumens and yield per lumen/square ft.

I would need to know exact tubes you are using to say anything for sure. Im not following last development on T5s, but most red T5s Im aware of actually continues emitting blue and some red light. Some of them, noticeable amounts of yellow. By placing white and red T5s intercalated 1:1 or all at each side, for such number of tubes there going to be little difference between areas of the grow. Yes, different spectrum on each side, but not extreme differences at all.

But I think we are highjacking thread with this question, why about opening a thread on the topic?
