No, I'm suggesting something more subtle -- a test that deforms the skis using shocking impacts, yet doesn't cause delamination.* That, I suggest, might better replicate what skis experience than a conventional cycle test (or at least capture an aspect of what skis experience that conventional cycle tests don't).
*That's why I recommended using large blocks of wood to distribute the impact over the entire forebody and tail, rather than what you describe, in which a steel plate is use to concentrate impact forces at the tip. And you can also reduce the impact force (and correspondingly increase the impact time, to achieve the same total amplitude of deformation), until you find a force regime well below that at which delamination occurs.
