Oh, you said "product" -- I would not recommend doing this in any sort of product. That is just going to lead to frustrated customers and possibly equipment damage.
If there is ONE connector family one should NEVER misappropriate, it’s USB, because you can pretty much guarantee it WILL get connected to an actual USB device or power source, causing it to not work at best, and damaging one or both devices at worst.
Oh so you mean like using the USB-C connector for different things on different consumer electronics devices? That sounds familiar. By standard USB-C only needs to support USB 2.0 to meet the spec.
But if the device so chooses it can also have the flowing:
-USB 3.0
-USB-PD power delivery(from 5V all the way to 20V 5A, varies on what is supported)
-Thunderbolt
-HDMI
-DVI
-MHL (Another digital video format)
-Analog video (VGA, Component, Composite...)
-DisplayPort
-Debug Accessory (Like JTAG)
-Analog line level audio
You can plug any two USB-C devices together using a cable, but it will only actually work correctly if both devices support the same features from that list above.So in this regard USB-C is already fucked from the start. Only guarantee is USB 2.0, everything else is a gamble.

So if you come up with another feature for USB-C there is nothing really wrong with it because everyone else has already thrown compatibility out the window already. Just make sure you respect the 5V GND and CC pins so that nothing blows up if plugged into a USB-C port.
