I suppose one could but depending on the type of synthetic stock it may cause problems with splititng around the edge of the stock. It's not too hard to afix a regular butt pad to the end of the cut down stock. Some of the over molded stocks are very flexible and most times glues won't stick. It that instance a filler block can be added and glued in place. This stiffens the butt stock enough to hold the butt pad ok.
