What a bonkers idea. How about we make sure it can do everything from the non-moving non-saline predictable environment of an airfield first and then move on to other stuff.
The foreplane comment shows how ill informed some of these posters are. The things sit forward of the seat. As for thrust vector to reduce landing speed? The leading edge slats motor themselves back up when the gear travels to increase landing speed at the moment, because with them out the nose is too high to safely see the runway. The slow speed capability is already there, the forward visibility is not and thrust vectoring would only increase the weight of the jet (which further increases the stresses on the airframe etc). Besides, add salt water to stuff that wasn't designed to operate in that environment from the start and it will break.
Buy a tried and tested platform rather than getting typhoon to do yet another job. Jack of all trades etc...
