Applying to same school as post bacc RA position

I am starting (very early) at looking for post bacc RA positions. I am very interested in underachievement among gifted adolescents, which does not seem to be a big research area.

I know beggars can't be choosers, but of course I am hoping to find something that is at least involved with adolescent research.

Duke of course has TIP which would be a fantastic research experience. I live in NH so I am close to some great child research centers, (Harvard, Yale, etc).

Now my question is....if I were able to finagle my way into my dream research position, would it hurt my chances at all if I were to apply to the same program affiliated with that research?

Thanks!
