It does make sense that they cannot change the size of their gems, even with shapeshifting. Unlike their bodies, their gems are actual psychical objects, and thus aren't as flexible as the light-based forms of the characters. I think its great that the animators actually took that into consideration ( plus, it looks hilarious ).
