panel in garage

[jetlag]

I have a house with built in garage with living space above , The code calls for fire rated drywall in ceiling , the wall are concrete block, I wanted to mount the main panel on the garage wall inside . I hate run that many conduits up the wall to protect all the home runs, it will be a 42/42 filled. I had a plan to install 2 , 2x6 treated studs against the wall from floor to ceiling and mount the panel in between ,the box will be covered with drywall floor to ceiling , The 2x6 will leave room to bring cables down behind panel to the bottom knock outs. My question is can I leave the box open at the top inside where the cable enter the area above the ceiling , the outside of box will seal to the ceiling dry wall. No fire can get above the ceiling without going thru the fire rated rock on the box . but the cabels could burn and get thru with no fire chaulk

How would you do this panel, do you know a better way, what if instead of small conduits i use several 2" , there is a place in code that all allows this as a sleave , I think the length is max 10 ft and has to be out top of box and ends sealed. I would have to cut the 2" holes
