The Lutron Grafik Eye would be my choice. Prob in the $1500 ballpark, installed, by an electrician who has installed them before.
One-to-one swap of the bank of switches, no fancy wiring or switches in the closet.
The keypad(s) on the front of the GE are for selecting programmed favorite scenes. If you ever need to, you flip up the cover for adjusting single loads.
But, I have to ask - it looks like you have multiple rooms or closets. Why do you want to put them all in a single bank, and not where they would be most useful?
I can understand some of them centrally located, but not all.
I would hate not having scenes, with that many loads in a single room. I'm currently renovating my kitchen, using Lutron RA2 and a few keypads. My wife doesn't like the look of the GE.
Finding an electrician who has used it before will cut down on GE selection/design time, and reduce frustrations with controlling LEDs.
GE is available in multiple colors and button configurations. There is too much to learn to DIY, with limited time. You would need to find someone experienced.
