I don't think so. MH has it's pluses and minuses you need to weigh against T5s. MH produce a nice shimmer in the water and in my opinion, have the capability to produce nicer colors. But MHs also heat up the tank more since the heat is coming off of a point source instead of spread out. And since the Nova Extreme Pros have individual reflectors, which increases the light output per watt of electricity consumed, an equivalent MH will be more expensive and use more electricity.
I've had tanks with T5 only, MH only and MH/T5 combo lighting before, and I prefer T5 only.
