It is not worthwhile unless your bike is unrideable. Every bike feels a little different, you can get used to bikes with quite flighty steering.
^^^ what you said
you can have steering dampers but tank slapping is a motorbike curse. don't mess with the headset when it's properly adjusted that could really hurt, just change the fork / stem / seat position as said above.
