Although not ruling out Europe it is worth pointing out that you could fly to taba, head south, drive around the Red Sea and get to Jordan, via nothing but Islamic countries, and then get a ferry from Aqaba to Nuweiba (sp?). so you would have done the whole red sea except for 15 miles or so. In fact I reckon you would be ok to get through Israel going in that direction but if you went the other way I think you may have issues getting into Saudi, having already been in Israel.

In reality the real problem with that plan would be the time it would take versus how much time you would need to do it justice. Not to mention the fun of getting permission to enter and travel through Saudi. But if you could pick up a local guide in each location it may be possible.
