LED layers

Is there a way to make a profile that lets me do custom key combinations in a function layer? What I mean is that I want to hold down the super key and light up all of my keyboard shortcuts for window management in Linux. I was trying to do it with function layers and the DKS but I wasn’t getting anywhere with it. I just want to be able to hold down my super key and the leds light up my shortcuts, then when I hit that key it sends a super+return for the return key or super+q for the q key.
