depends on budget and time frame. My grandson did exactly that and upgraded most everything between the studs before 'rebuilding' the interior.

Now most would consider things before they opened the walls but...have you considered hot and cold running water? Where are you at in this process anyway? What does your architect suggest you consider?

Based upon what I can see, consider hiring a local architect.

Is this a house you have been living in, or new to you. If the former, what has been deficient or missing? Of course, consider electrical, plumbing, and hvac.

I don’t understand the question. Are you referring to electric, hvac, plumbing.... or aesthetic finishes?

Confused here - there seems to have been more content in this thread. I didn't see anything about demolition, etc. in the only post by the OP.
