My home has several fuseboxes in different locations. The original knob and tube wiring (where accessable) has been replaced with two conductor wiring (no ground). Still kt in the ceilings though.

I would like to replace portions of the wiring with modern grounded wire which will allow me to use grounded receptacles.

The fusebox does not currently have an earth ground. Can I add a ground rod and a terminal strip (near the fusebox) to attach the ground wires for new wiring? Eventually, I would like to install a new 200amp service panel and then this would all go away. I was just wondering what my options were. Any thoughts on partially modernizing an old electrical service?
