Looking forward to trying this.
There is a Spitfire T.9 in the big Just Flight Spitfire package for FS2004, and it works in FSX also. It can be flown from the back and is quite fun, I do it occasionally.
I'm not aware of a TF-51 or any other dual WWII fighter conversion that can be flown from the back in the sim.
The great Eric Brown included his impressions of flying a G-12 from the rear in one of his books. Based on that, it would have been quite a bit hairier than either the TF-51 or Spit T.9. There is now one Buchon flying with a G-12 style second seat, I don't know if anyone attempts to fly it from there or just stuffs passengers in it, but it would provide some indication of the experience. Unlike the Spit, the rear seat in the 109 is not elevated over the front cockpit, so you are much more blind. Brown recommended using a large airfield and not attempting to use a runway or stick to any exact heading on takeoff or landing. Just aim for a generally unobstructed area, feel your way down by looking out the side, and expect everyone to get out of your way.
