ok, you would probably have to build a little box or cover for that then use something like this

You buy the glass separately, shorten to its min hanging, and maybe paint it brass. you also keep in mind you cannot hang anything too low there....the door will hit it, best to measure your max drop. you may have to go with a flush mount. You need a creative electrician or, to repair and replace the whole show..

Thank you so much!!
