Frankly, it sounds more like you are looking for a "good deal" rather than a good career. If this is your motivation, I would politely suggest that you are looking at the wrong employment.
I'll apologize in advance if there are circumstances that I don't understand but the reality is that, should you apply for ROTP, the military will decide where best to educate you and it will most likely be at RMC. If you really want to go to a civilian university then you should do it; you can always chose to join the CF after the fact under the Direct Entry Officer program.
