can I add a zone like this?

Please refer to this diagram (attached or this link) to see my existing piping and my plan to add a new zone:

We converted from oil to gas last year and now we are thinking add two rooms into the system as a separated zone. It is a hot water heating system.

Please tell me "Option 1" is valid or not? if not, how about "Option 2"?

2 is better. But, you only run a return from the baseboard you add. Not a parallel from the loop like your drawing shows.

Where your drawings hows the line from the circ continuing and running back to the boiler near piping. You would stop it, at the beginning of that last baseboard.

Don't forget the flow checks.
