The only problem with that is you're not going to know the height of your lights until you get it on your tank, with your particular plants and you can't adjust it with your current stand design.
Yes, X amount of lights will put out Y amount of par, but everyone's water is a bit different, CO2 amounts are slightly different and that will drive light position. I have a shop light above my tanks, no CO2, but I've adjusted my light position probably 5 times via chains it hangs on until I got the right amount of growing a bit of algae on the walls of the tank for the shrimp and growing algae all over my java moss. If your plants aren't big cover plants, you may need to raise it. Go with big cover plants, may need to lower it. There is no way to say put it at this height. It's a trial and error thing.
