That's actually similar to what most people with Halide and T5 combo units do, isn't it? That's kinda what I do.

My 22K T5s are on from 10am to 10pm for my viewing pleasure.
From 1pm to 8pm the 14K halides are on for growing. The only difference being that my two photo periods overlap during the "growing" hours.
