Baragon vs Gorosaurus

This is the Gorosaurus from the "Paris or Bust" model kit my friend Charles gave me that depicts this scene from Toho's Destroy All Monsters.   
I am building this with a twist, I made the hole bigger and I took the extra Baragon head from an Overground kit I haven't built yet, casted part of the body too, But my mold was only big enough to make the hands and back.  Also, the claws did not cast well.  So I had to sculpt the arms, belly, claws and upper thighs myself. 
This is not how they will be posed in the diorama, it will be like the screen shot above, but Baragon will be like pushing him back down the hole.
What do you think of that idea?
