IF:

Yes, the gas giants of the Sol system do have dense cores, but those cores are made of gasses being squeezed into a metal by the pressure of all the gas on top of it. A state that can only be sustained with a large enough amount of gas in one place (aka. a giant planet). Strip off the outer layers to a small or tiny sized core and the metalic hydrogen decompresses (quite spectacularly I would imagine) and you are left with a rather large storm.

Granted, there are some trace amounts of the hesvier elements in the various cores, but these are negligible compared to the vast amounts of hydrogen and such.
