Great work Bocephuz, and the evidence of a quality post is the informative discussion it leads to. You win!
A few thoughts:
RT to improve the overall quality of the line, its a no-brainer, do it.
Teller has much to work with, he seems to have grit, game smarts, and he certainly has the raw strength to work with---if he becomes a Richie Incognito level player "on the field," that position is set for a good number of years. But, I would apply the same logic above about DD here, if a better LG is attainable, then yes, move Teller to the right side and the entire line improves.
I think Bodine is serviceable at Center. A bigger priority is the right side, however that can be done--new people there, or the move options mentioned above.
As a few have said, although the preferred way is to slot people and let them grow, the biggest objective is to get the five best O-linemen on the field. Doing so may mean changing a few positions where it makes sense.
The team now has franchise level QB talent, now it needs to give him the maximum opportunity to grow into that. So, no matter how you do it, get your five best players out there.
