Once you get the LCD/digitizer assembly off the tab, the procedure is pretty much the same as in this thread for the Nexus 7 (2012). If you follow the procedure laid out therein, you should be able to separate the LCD from the Digitizer. The trick is to do so without damaging the half that still functions.
Don't believe it cannot be done because the parts are "fused" together. They are not; they're bonded together with optically clear adhesive, same as phone touchscreens. There are at least 3 different ways to go about it, depending on what you have at hand. One member even stated he separated the two by accident while cleaning the tape residue off the digitizer, and the cleaner seeped in between to dissolve the bond.
Try it first, and if you fail, you can always pay for the whole assembly later.
