Jetset I guess it depends on your Career L Officer.
To be honest I have heard lot of things about CLO's attempting to push people into x,y and z. I found the one that I have been allocated to absolutely superb, that cares thoroughly for the Service and also the candidates he puts forward. Now the question of Warfare Officer was only bridged if I fail a medical for grounds such as eyesight.
I was never asked whether I would consider anything else apart from Flying. I was told to stick with you aims and to not fall for anything such as U can then become a pilot in 3 years time. The training alone takes a good part of 4 years and maybe longer. Be confident, be positive and stick to your guns over flying.
All I can say really,
