The FTR (now JHL) requirements have not changed much. As the weight of the FCS has increased, the lift requirement has increased as well.

I'm wondering about the shipboard use of the FTR tiltrotor, because, AFAIK,
the high disk loading of the Osprey is a consequence of the limitation of
the overall span. A larger rotor diameter would have been prefered, but would
have caused problems on a carrier. Are these limitations obliviated for the
FTR ? ???

Indeed the original Army V-22 requirement had a larger wing and prop rotors. The USMC amid-ship island clearance requirement drove the design for shipboard operations as you indicated. The JHL is expected to be able to operate in the maritime environment. Studies are ongoing into how well the JHL will be able to work in and around a ship.
