If I understand your description properly all these lights are already on the tank, you just want to re-arrange the layout
Not really necessary and won't have much effect on the growth of coralline. Coralline will respond better to water chemistry maintenance as well as bulb spectrum. Light intensity has nothing to contribute.
If you have lower light corallines like green, light pink, orange or red they will prefer lower output lights in the 6500k range.
The highly desired (by some) purple coralline will repond better to higher (bluer) kelvin bulbs at 10,00k+. They will actually respond the best to "true" actinics.
Since your lights seem to somewhat cover these area's of the spectrum, I would think the chemistry may not be optimum for growth. Alk
and magnesium levels must be maintained. It will also help if you spore
the tank by slightly scraping the existing coralline to release it into the water column and allowing it to spread. Turning off the skimmer would be best for a hour or so while doing so as it will pull the spores out of the water.
