RAM: I don't want to sound harsh, but I think you are hoping for the unobtainable. I do know a few navs who crossed over to pilot, but only once they proved themselves after an operational tour, and found themselves at the right place, right time. As a stude out of cranwell, I really doubt if this is possible - made worse by the current climate.
Nav training is not going to be a breeze - you will have to earn the brevet. In fact, I know more chopped navs and navs that have quit than pilots who have been chopped. It is very hard work and it is a tough course. If you are going to succeed, you are going to have to focus on it and want that nav brevet, not just see it as a route to two wings/the airlines.
