I've thought of that before and looked into it somewhat. To do it for the sake of learning about Moto Mods and create a prototype for educational purposes would be worthwhile. To do it for commercial purposes, I don't see having that feature alone as a mod to be cost effective. For the price of a Moto Mod development kit to get you started, you could get many USB Type C IR Blasters. Once you get the hardware working you'd then have to write software to get it working with any equipment you want to use it on.
Once you get started and need some guidance perhaps some people here can assist you.
