Putting A MIDI Keyboard Connected to a Car Horn
 

So, I had a stupid thought when me and my best friend were talking about exotic cars a while back, and I had this wild thought. So, people have car horns that change, and play custom sounds, what if I just had a horn that was controlled by a 49 key MIDI controller in the center console, or even the dash?
Now, while it is, admittedly, a stupid gimmick, I think it would be a lot of fun, especially if it had a good polyphony, of, say, 10, or so. You'd be able to put out full scales and such. What better way to practice in traffic then to have your car be the instrument?
Anyways, looking into it more, most car horn modules only play up to 5-10 sounds, so you'd need to buy 5+ of them, rewire them, and hook them all up, even then, you'd have to go above and beyond and pitch them all.
Is this a stupid idea, or could it be a lot of fun?

Omg do it and play this

Get a horn speaker and a mono amp, then run a cord through your firewall and connect it to your keyboard, which would be powered by some sort of AC plug in your vehicle.

Like this, but switch out the button module for your keyboard:
