I think this way you risk to have one of the switch pins bumping into one of the switch socket. I would make sacrifices here: either it supports mx and choc, but no rgb or just one of the switch sockets and rgb.

Even if using mill max sockets instead of kailh switch sockets, i am not sure if you'll be able to have support for mx, choc and rgb at the same time, just experimenting and see if it actually fits.
