Adding Paddle Shifters?

[absentmathis]

I’ve seen this discussed on occasion and searched around a bit but haven’t seen a definitive answer...has anyone successfully retrofitted and if so how hard was it? I would never have sought this out, but I’ve come across a nearly new X5M wheel that has paddles. It looks like virtually the same wheel I have but is in better shape, and all else equal the paddles seem like a neat, albeit frivolous in this car, feature. Any input appreciated.
