They decided that the only thing worse than losing the competition was winning it.
Part, but by no means all, of Comanche's problems came when they dumbed down the original specifications so as to insure that no one would offer a Tilt-Rotor. In doing so, they put in weight and power constraints that made a Tilt-Rotor non-competitive, The maximum allowable weight and power allowed made something other than a conventional helicopter non-feasible especially when they changed to give no extra credit for significantly exceeding requirements. Ironically, the weight and power specs had to be relaxed for Comanche anyway. Of course any type of airframe they did build, regardless of technology, likely still would have had many of the systems and avionics problems and deficiencies (like a gun that couldn't hit a target) Comanche had.
Bell has shown a number of concepts and models of heavily armed Valors. It would just take someone (USMC?) to say, "Go ahead, and here's money". Keep in mind that Valor is a much larger craft designed for a different mission. A Tilt-Rotor gunship also has a major oft overlooked advantage over a helicopter. While it's really complicated to do so on a helicopter, it's trivial to fit off-the shelf-ejection seats to a Tilt-Rotor.
Tilt rotors are plain silly, except for semi-tactical/strategic transport from a ship where higher distances (over a flat sea) can be covered more quickly. I still cannot imagine a tiltrotor doing 100kts NOE…. And with NOE I mean real NOE, so not at a 100ft but 20ft, being agile enough to really follow the terrain like a Huey or Blackhawk could.
