2012 LFX V6 - From Camaro - Manual Trans. - E39 PCM - CANBUS - Run stand alone?

[Raydar]

Searched "stand alone" and didn't find anything useful.

Has anyone successfully gotten one of these PCMs to run stand-alone?
I'm considering a swap into a different car, and would prefer not to use the BCM, ABS, and all the other modules that it wants to talk with.
Is it as simple as looping the data bus wires back on themselves, as some have implied?
I've considered other CANBUS swaps, too, but I have never gotten a concise answer as to how difficult it is to make it work. (Other than someone telling me, "Yeah... I can probably do it. For a price.")

Any help will be appreciated. (I specified 2012, since Tunercat has the VDF available. :D)

Edit - My apologies if I have this in the wrong section. Perhaps it should be in OBDII...
