Bad idea I tried that and it just folded the penny into a neat shape and I had to tap it out. I heard someone saying dimes were another option but I don't know that will be a great one either.
CWP-7 from Park would work well and save you space in the tool box so no need for CCP-44 and CCP-22 but you could get both of those and be set CCP-44 for ISIS and Octalink cranks.
Also if you need to remove a lockring it happens to be the old 8 notch XTR tool
