Since most of this mass happens to be at the end, effective mass of the tonearm can increase to 19-25 grams, or so.
You can not change effective mass by adding heavier headshell, the effective mass in not just a mass, it is not that simple to change effective mass and it was explained here by experienced users.

I will add a few pictures, i use all those shells, i have EPA-100 mkII tonearm.
Most of the shells i have listed are lightweight, especially the
Orsonic (light version, not the heavy one), Stax (with azymuth/overhang adjustment), Grace HS-6 (carbon), and Technics own vintage Headshells. This
Kenwood headshell is great to match in color to the new Technics arm (LOL). Victor headshells are also nice. They are all about 10-12g max. No problem to use them with Technics tonearm. You don’t have to stick to 8g headshell, just because Technics shell is about 8g! 10-13g is an average mass of the shell in the modern world.
ZYX LIVE-18 is great high-end headshell, but very expensive.
