Thoughts on hidden mods to original games?

Have a bunch of full games I repaired. I mostly sell to other collectors or rich older folks that want to deck out their basements with oldies.

I have been trying to think of additions that might increase the usability of cabs for the entire repair and sell industry. But, I also love the idea of keeping machines as OG as possible.

Been thinking about adding hidden magsafe and qi chargers into the control panel, where it doesn't actually effect the artwork. And on the backside, I was thinking that USBC and HDMI video out in a sleek panel would enable people to easier stream games without needing to put a camera on the screen itself.

Is this blasphemy or do you guys have any ideas to get more utility out of our beautiful beasts?
