You mean the entire case with the inside components and battery and ports and trackpad and keyboard and speakers, including all those innards?

It is possible, you probably have to buy a similar MBP with a damaged screen or buy a new or used MBP (which you could just use instead of the damaged MBP) or get all the parts (logic board, case, bottom plate, battery, trackpad, keyboard, ...) individually.

Look at iFixIt and its guides for Mac notebooks.
 
go to the apple store , the top case is 169$ plus 40$ labour, ebay will have then for around 140$ your choice.
