Hi Student_32,
Please don't worry about academics claiming your project as their own. I have emailed my detailed proposal outlining literature review, methodology, data collection strategy, data analysis etc. in great detail to various Universities and academics and have frequently received a polite reply stating that though the project is very interesting; it is outside of their research expertise - (I assume) basically a standard reply to those whom they do not wish to supervise for whatever reason. This does not at all mean that they are planning on running your project! As Maccle pointed out - it would appear extremely unprofessional and may impact you in the long run. Good luck with your application - hopefully, you will be accepted by a University very soon!
