Yeah, right, I'm going to resurrect a 60s cargo behemoth that won't even fit in any icon format or have any tactical use at game scale...
The basic concept is sound however; really BIG compound helicopter designs have been proposed for HLVTOL:

The HLVTOL is an aircraft with the ability to deliver one FCS within a radius of 1,000 miles [1,600 km]
...
During the 1997 war game at Fort Leavenworth, friendly forces employed HLVTOLs with speeds of over 120 mph (miles per hour) over distances of 900 miles to deploy the FCS. The opposing force commander quickly discovered that he could not counter this by fighting conventionally.
....
Bell Aircraft has proposed a Quad Tilt-Rotor able to lift 90 personnel or one 12.5-ton vehicle to an un-refueled range of 610 miles at 320 mph. While Carter Aviation Technologies has proposed a compound helicopter called the "CarterCopter Heliplane-Transport" to carry 22.5 tons 1500 miles at 450 mph.
Called the CarterCopter Heliplane Transport, the rotorcraft takes off, hovers and lands like a helicopter. At speeds above 100 MPH, the CCH-T converts to a CC high-technology gyroplane by unloading its rotor onto very efficient high-aspect ratio wings and (in the process) slows its rotor to minimize profile drag and maximize flight efficiency.
The CCH-T would be the largest rotorcraft ever flown. Its size, design and capabilities are impressive by any standard. The aircraft is taller than a four-story building. The main wheels are six feet tall, the two props are 24 feet in diameter and the rotor is one-half the length of a football field. A fully loaded Greyhound bus can be driven up its ramp and parked inside (with room to spare), and then flown away - straight up. Once airborne, the CCH-T converts into a CC gyroplane with flight efficiencies equivalent to fixed-wing aircraft. The CCH-T is designed to cruise at 450 MPH at 30,000 ft altitude and carry a 45,000 lb payload for 1500 miles with a 45-minute fuel reserve.
The CC prototype was built as a proof-of-concept demonstrator for both the CC ultra-high-inertia rotor and the control system interface between the rotor and wings. Other innovations on the prototype include the CC high efficiency prop with a computerized prop controller, and the extreme-energy absorbing landing gear. On the CCH-T, the 24-ft diameter 4-bladed version of the same prop will produce over 40,000 lbs of static thrust (per prop x 2 props).
--------------
Basically, Tilt Rotor stuff like the V-22 really doesn't work; and is only a marginal solution; because of two things.
1.) Unless you make the entire wing tilt upwards; you're going to waste a lot of thrust downwards which will just hit the wing and dissipate.
2.) Propellors and Rotors are designed around two entirely different flight regimes; any attempt to combine them into prop-rotors like on the V-22 will result in a marginal performer, which will be average in both regimes.
For a serious heavy lift VTOL to have speed, range, and payload, it's got to be a compound aircraft like shown above.
The Soviet Rotodyneski!
