Personally,
If you haven't done the work, then my recommendation is not to list it in the volunteerism section. The committee may think your are trying to pad your application.
The best place for your future plans is the personal statement. It also makes an interesting interviewing topic. The last thing you want is someone on the committee to think your dishonest. Remember, your application and LORs are the only pieces of info they have about you prior to the interview. If someone believes you are trying to pad your application with things your planning to do, they my remove your app from the interview list.
I realize you really want to them to know your genuine interest in volunteerism, however taking a chance at making a negative first impression isn't worth. They may be impressed with your ambitions. However, if they feel you are being dishonest, your chances are shot. Why take that chance?
