My impression is that LinkedIn profiles are simply click-bait for recruiters. So I would suspect that your proposed profile changes might reduce the number of unsolicited emails you get.

I only use LinkedIn to reconnect with colleagues from past jobs and very occasionally read posts to the few groups that I have an interest in. Basically I use Facebook for family and friends and LinkedIn as a sorta facebook for "professional" connections. Keeping the two spheres of my life quite separate.
