Answer: I doubt it, but...
Why enroll in DEP if your ultimate goal is to be an officer, whether through USNA or otherwise? My (unsolicited, know-nothing 2ndLt) advice is to wait it out and cool your jets. I get that you'd want to get out there and do stuff if USNA doesn't work out but there's not any real "point" to doing so through the DEP.
You're also entering DEP planning to break your contract. There's nothing legally wrong with this, but it's strange to me to enter something like that with the intent of reneging on what you said you wanted to do.
