I'm not sure if it's possible but I'd love to be able to connect a wire to a miner and have the Circuit connection pop up with the ability to set filters. I'm currently running a mod that sometimes gives extremely mixed ores. The ability for my base to set filters to say what we should or should not mine would be amazing.

I'm afraid that is way outside the scope of this mod. All this mod does is enable engine functionality for drills to filter. Something like that would be a lot of runtime scripting which I'm not interested in doing, and wouldn't be great for UPS either. You could ask on the forums for this functionality to be implemented in the engine: https://forums.factorio.com/viewforum.php?f=6
