You can never prevent a collision. It has less to do with stiff blades and more with rotor disk tilt. You'd have to further separate the rotors, but then I think you start losing some of that counter-rotating rotor efficiency.

Here is an old NASA article on Coaxial rotor systems: https://ntrs.nasa.gov/archive/nasa/c...9970015550.pdf
