I have to admit that I would not be optomistic about such an effort's chance of success. Perhaps I am already too jaded by my experiences in military procurement and procurement politics. But I would certainly be glad to help in whatever way I could. Although an engineer, I am not an automotive or mechanical engineer. But those engineering details are quite a few steps down the process.
At this point, the biggest issue would be deciding exactly what the requirement of any new vehicle is. For example, the requirements for an armored patrol vehicle would push the vehicle to be smaller, lighter and more manueverable. Visibility would be more important than cargo capacity. The requirements of the general utility vehicle push it larger, and then by necessity a little heavier and perhaps less manueverable. A general utility vehicle's cargo would be more important relative to a patrol vehicle's. That is not to say that these issues cannot be reconciled, but hitting the right point on scale between them to compromise is very important. Or perhaps the decision that we really need two different vehicles (which I personally don't think, but a case could certainly be made).
If someone wants to start collecting information from the troops in the field on that subject, I would certainly be interested in reading it. Ask them about they think an armored peacekeeping vehicle ought to be able to do. I fear that most of the input would be 'tainted' by limitations of the equipment they already have experience with.
These seem like a good start:

The sloped sides seem like a good idea. They appear to be produced with a high degree of OTS parts.
If they work for the Israelis, they must be pretty decent in the terrain of Iraq.
