Backspace never belonged there and Colemak is dumb for not mapping control (much more useful) onto caps lock.
Also, what's wrong with just using your ring finger for C-q, C-z, or C-z? It's not like you're even typing words so you're not really touch typing anyway and keeping it flexible sure doesn't hurt (you don't type "cd" on qwertz with two fingers? What the fuck is wrong with you?).
