Remote Control Modded PlaRail?

I keep seeing train sets offered on eBay that have model trains with remote control in the form of a small hand held transmitter.

It just makes me wonder if any of you fine folk have ever thought of buying one of these and transplanting the remote control circuitry into a normal PlaRail model to give you a unique remote control PlaRail train?

Come to that some of these sets also come with sound and smoke in addition to the remote control, maybe these smoke and/or sound units could be transplanted as well, what do you think?

Here's a couple of example sets that can be had for very little money that have the features I mention;
