Lighting panel for switches
Don't use the breaker panel.   Use a new breaker panel in a location of your choosing.  

You'll need 4 wires from the existing breaker panel to the new one.  You'll need 2 spaces for a 2-pole breaker in the existing panel.  If protective devices like GFCI are required, those can be part of that 2-pole breaker. 

Then, you basically use the new breaker panel as a switch bank.  

Naturally, it can double as a proper breaker panel. You'll need to put 20A breakers or 15A as appropriate to protect your various branch wiring and devices.  If you have call for a 30A piece of equipment, you can do that too. 240V, not a problem - you'll have both legs.  

Also the breaker panel will make it ridiculously easy to add additional new circuits as the need arises -- provided you use an extra large panel with spaces to spare. Because spaces are cheap and regrets are expensive, we very strongly recommend to "Go Big Big Big" when selecting a panel. Finishing the project with half the spaces unused is a good sign you sized the panel properly.  

If AFCI/GFCI requirements allow, you can also use "double-stuff" breakers as an aesthetic choice to remind yourself which breakers are lights and which are receps.   

If you are switching HID lighting (mercury vapor, metal halide, low/high pressure sodium), or old school fluorescents with 5-pound ballasts, then you must use "HID" rated breakers.
