There are players that did this and are quite expensive or out of production and need to now be found used. They will work with some disc material but anything streamed is embedded in the stream. Also if you watch Netflix or Amazon or all the rest the controls for a scope movie when you pause etc will be down in that area.
If you have a mask down there for an IMAX +CIH setup you can remove it. if you have a mask for a CIH setup you can overlay a white mask for the sub titles to show on. You can shrink the image as you mentioned and I agree that is not the best.
I personally looked at all this and for my needs went with variable presentation and a stealth screen surface. That solution worked best for me as my budget didn’t allow for automated 4way masking and my laziness didn’t allow for me jumping up changing masking every time the media changed AR.
