You could go with the Disneyland style Connie and George as seen at the Haunted Mansion 40th Anniversary event:



If you go with the beating heart... find one of those rubber hearts and shove a flashing light into it.  I did something similar for a Halloween display and it worked fine.  You can also find flashing heart props (I think I got mine at Target), but it does cycle through red and blue which is NOT exactly authentic to the attic bride.

Edit: corrected typo and added NOT authentic as that is what I meant.
