You can certainly use high-tech lines for lifelines—since the Spectra/Dyneema lines are stronger than the same diameter steel rope. However, most stanchions are going to chafe through them in rather quick fashion, unless the holes the lifelines pass through were fitted with tubing liners.
That could easily be done to your stanchions, where a small section of stainless steel tubing is welded into each of the holes that the lifelines passes through and the edges of the tubing flared and rounded to reduce chafe, but it would be an additional, one time expense.
