You could use separate profiles on Firefox (which I do, I have half a dozen) and in each profile set up different browser headers. Everything coming from the same IP address would still be an issue, but I doubt that trackers rely on that alone as it's too coarse. Families will easily have 6 - 12 devices for several different people in the home all NATed through the same ISP IP address. You could use proxies if you're really worried about it.

My project does that.[1] Since each profile has its own profile.js and extensions. One application is that I hate triggering financial portals to re-authenticate. So all of my finance happens from my home IP, no matter where I am. And instead of a heavy VPN, it is just an ssh tunnel. When I was in university, my school browser profile always routed through my school proxy. If I start using facebook again, I will use Facebook's TOR public gateway, but only for the Facebook profile.

Device fingerprinting (and cache attacks) could still connect the different profiles unless you change more parameters than just headers. Or disable javascript for some or all the profiles.

Like I mentioned in parent comment, my project has had a lot of success with that. I know I was able to fool the Evercookie[1]. I can even have different profiles have different browser engines if I want. They each use individual prefs.js files.
