Can I repair the manual zoom control on the shutter button?

I dropped my Nikon Coolpix L310 and broke the manual zoom on the shutter button. I have a L120 I dropped in the ocean that looks really similar. I was thinking about trying to replace whatever part I broke from the old camera. The zoom control is no longer spring loaded. The shutter button still works, although feels a bit different. Is this something anyone else has tried?
