I asked the question a few months back about the viability of a FBW enhancement which slowly deploys the spoilers in situations such as this to "help" the plane onto the ground.
I was dismissed out of hand and I am sure my sanity was called into doubt in private!
Imagine my surprise when, a couple of weeks later, I read of exactly this technique being deployed (contrary to SOP I should add) on a floating landing like this into Grand Cayman. Aircraft was a 737-300. It was calculated that the captain's actions saved an overrun!
