I've done a number of swaps of steering wheels, most recently, I put my 04 F-XT's wheel in my son's 2001 Outback. The wiring harness did not match up but luckily the airbag itself was the same size so I only swapped the steering wheel and used the old airbag. Myself, I won't cut and splice wires. I'm not willing to risk an airbag not deploying in an accident just to have a nicer looking steering wheel. Personal choice is all. The only way to find out if it will actually work or not is after the fact. I have a feeling if there is a fatality and the airbag doesn't go off and they find out it was modified there could be legal ramifications. Just conjecture on my part.
My previous links stopped working when they did a server swap, here are new ones:
