Recently I took a wall plate off a 4 switch box to paint the wall. When I did this, I found that the wall plate was being held on by paint alone.
It appears that 4 light switches were installed in 2 adjacent double gang boxes. There is a stud on the left side of box 1 and a stud on the right side of box 2.
To get things stabilized and provide a way to attach the wall plate, I installed 2 mud rings (shown in the picture).
However, I quickly realized that the 4 device wall plate will not cover this now that they are seated properly. I tried initially to fix this by cutting a standard 2 device plate and positioning it next to a standard plate:
Q1: Is it possible to replace the 2 gang boxes with a single 4 gang box? I'm hesitant to go down this path because my instincts tell me that there is a reason why someone did it like this.
Q2: One other idea I had was to combine some of the switches. Three of the switches control recessed lighting in the room and we rarely turn on one without the others. So, I'm considering combining those 3 into a single switch. I read a few other similar questions but I'm not entirely sure if I can do this. Outside of verifying the switch can handle the load, what other things do I need to consider? Would it be simpler/easier to do this rather than replacing the whole thing with a 4 gang box?
Thank you for any help you can provide!
