Popularity has nothing to do with it.

Heat does...........
So with that in mind, using less light does really seem like a better solution.
There are many species one can use, why change everything and force yourself into a situation for one plant?

There are going to be trade offs for every situation.
Addressing those trade offs and goals is another matter.

The trade offs might be worthwhile for you if you have a certain goal, however, often such trade offs are more like a barrier that folks put up in their own way due to frustrations or belief.

I must have high light!

Try 2-4 bulbs instead of 6, I'm certain there's not a plant around you cannot grow just fine using 4x 54T5 bulbs on a 75 gallon tank.

Having more of a potentially limiting nutrient seems like a better approach than less for CO2.

At least as far as stability.
