That was my thoughts too, I had always thought the V-280 was a proof-of-concept demonstrator and now it's done it's final flight test that's what it seems to be. Mind you, it does open up a possible commercial line of tilt-rotor transports doesn't it ---
It would appear that Leonardo has elected to use this technique with their Clear Skies tilt rotor project.

Couldn't the wing/engine/proprotor combination just be transferred to the V-22 ?
Indeed it could. Would not be surprised to find out that this idea is being considered by USMC/USAF.

The V-280 has a pair of T64-GE-419s at 4750 shp. The V-22 has a pair of RR T406s at 6150 shp. (I could swear they were looking at the possibility of fitting the GE38, from the CH-53K, on them.)

The RR engines have been modified for vertical operations. While the GE engine "could" be modified as well, that is $$. Doubt that would be resourced.

Would the GE38 have to be modified to operate vertically, if they go with the same engine architecture of the V-280? I'd have thought just a new gearbox to handle the additional power

My main point was the hp difference between the V-280 and V-22. That would have to be addressed before swapping wings/rotors/engines.

But would it matter, just been looking at the specifications of both
V-22 empty 31,818lb V-280 empty 33,069lb
V-22 Max TOW 55,000lb V-280 Max TOW 57,320lb

I doubt it's that simple else the Army would have just bought V-22s.

@sferrin - my mistake. You are correct. If they were to revise the wing to V-280 format there would be no need to certify the GE Engine for vertical operations. A standardized engine would certainly be of benefit to the USMC I would think.
