Well I am new to aviation but if it were me, I would be very concerned about a couple of things. First off, with no instrument rating, the weather would have to be perfect over a tremendous distance. The chances of having a block of weather good enough over that far a distance are almost impossibly small. I am no meteoroligist, but that just seems very unlikely.
Also, I'm sure you have thought of this but if you were to overfly the middle east the chances of being shot down are very high. A lot of people don't realize that the Middle East is kinda like the wild west. In the USA for example, the military would have to be given permission directly from the Commander-In-Chief to shoot down a general aviation aircraft. However, in the Middle East, a SAM battery or tripple-A emplacement might open-up on you for the sheer fun of it, with no risk of accountability or repercussions. In some countries, private citizens have their own shoulder-fires SAM's that they found on the battlefield (!). I know this sounds completely nuts, but this is the Middle East we're talking about. There is even a documented case of a DHL airbus being hit by a SAM in Iraq. The pilots were BARELY able to get her on the ground. I believe there is information online about this particular event.
I don't remember if you said you would be flying over the Middle East or not but I would think that would be somewhat on the way. Now if you're flying a single engine piston they might not open-up on you, not wanting to waste a rather expensive SAM, although Triple A or simple machine-gun fire could be a problem. Your biggest risk would be people taking pot-shots at you. This actually happened in Vietnam...farmers would take long, low probability shots at American jets. The problem was, if you have millions of farmers doing that every day, eventually someone gets hit.
I would research this greatly before setting off over that area.
