Moving to the business forum.
While your description shows a few things that should happen, they do not define a full game.
The game is composed of thousands of little rules and procedures. Each operate within systems that are integrated together.
1) what's the general plausibility of this game being completed with a small team in under 6 months (at least a first level to kick it off)?
2) what level experience of a programmer should I be looking for?
3) if these don't cut enough programming to be possible as stated above, any advice on how to alter them so as to cut the burden?
1) Extremely low. For every game that gets finished there are perhaps hundreds or even thousands of people who make a list like that, and ask what it would take to make a game. As a percent you are looking at less than 1%. It is unlikely to happen.
2) Depends on the individuals. Depends on the quality you are looking for. Depends on the thousands of rules and procedures involved in the game that you haven't mentioned. Depends on the technologies they are planning on using. You will need more than just a programmer, you will probably need multiple programmers, multiple artists, a composer and sound provider, level designers, and QA folk.
3) Yes, gain experience. Go get one of the many rpg engines that already exist and learn what it takes to fill in the missing pieces.
My guess is that based on what you described, you would expect a level of quality for requiring a half million dollars or so in development costs just to get your first 'kick it off' version complete.
