Mark,
It's relatively straight forward, but does require some rewiring.

Unfortunately not. 
The OBC and mini-OBC use two separate wiring harnesses with different 
plugs.

To retrofit full OBC you will need a new display/OBC-box with the correct 
coding plug and at least the full-OBC wiring harness.
Optionally, you can procure and install the OBC-friendly turn signal stalk 
(push in to change OBC modes), OBC alarm horn and OBC coding box.

Feel free to drop me a line for details. I did the same retrofit on my 
ex-E30 6-8 years ago during three lunch breaks in a parking lot.
