If it was advantageous to use structures of those inside cells for reactions somehow, then some organisms would already do that.
Not necessarily. The space of advantageous biologically possible structural configurations seems to me to be intuitively larger than the space of useful configurations currently known to be in use. In order for a structure to be evolutionarily feasible, it must not only be advantageous but also there must be a path of individually beneficial (or at minimum not harmful) small steps in between it and currently existing structures. If an adaptation does not lend itself to linearly realized benefit, e.g. one that works really well but only when 90%+ is ‘correct’, it has no evolutionary way to piece itself together from 0-90%.
