Well, I do not have a lot of experience in those fields, but I know some things about aerospace and life in general. All those options are great, but not really related to one another. If you mentioned that you may take mechanical engineering and then transfer to aerospace, that would be more closely related. If you are going after energy and communications because there are a lot of opportunities close by, its OK, but do realize why you are making that decision.
My Dad once told me "He who chases 2 rabbits, will catch neither." If your passion is aerospace, than you need to figure out how to pursue that dream. If you are thinking about rockets and spacecraft, than you may need to think about moving to where those opportunities are. I know this may seem a bit extreme, and there are many things to take into consideration, but you need to be honest with yourself and be able to stay the course. Usually when you go for your masters degree, a lot of that will be based on, or a continuation of what you learned in your bachelors degree. I can't help but feel that you may struggle when you get there because you will not have the basics or a foundation to build on.
I have been very lucky that I fell in love with airplanes at a young age and have been able to make my life in aviation. I have had to move a few times, following opportunities, but they have always been in aviation. I have had set backs, but do not regret any of them because I followed my dreams and they have gotten me where I am today.
Good luck, hope this helps.
