Hm I ain't buying the method here. Not everything you do/say has to related to being a physician and getting into medical school. Interviewers want to know who you are as a multifaceted person, not just a drone who does everything in order to become a physician. If you're asked about a hobby, talk about your damn hobby and don't try to stretch it too far. If your research does not have direct medical implications, don't stretch it into some BS that relates it back to medicine. If you did scut work, say so, etc. As someone who's interviewed people (for entirely different purposes, obviously), it's just so annoying when someone does everything they can to stretch an answer to answer something that I never asked. Related 2-3 things back to being a physician. There is just no need to sprinkle in hints at every single chance you can get. You should be controlling the conversation whenever you can, but knowing how to answer questions directly without additional useless BS is just as important.
No offense but seeing as how you were 1 for 5 from interviews to acceptance, that corroborates my gut feeling that strategy does not seem like the best one to use.
