Option 1, is the less fuss, more upkeep option.
A change to the main part of one plan will possible mean you need to update the 5 or 6 other facade options as well.
Option 2, I can imagine there will be issues as you mention.
Option 3, I have used and it works well.
You 'pin' each option to a separate renovation filter so it only shows when that filter is active.
You will have to split dimensions and maybe duplicate some overall dimensions, but they can be pinned to the reno filters as well.
You can only ever see one option at a time and you have to remember it is all controlled by the reno filters.
I also use Graphic Overrides to change the colours for specific reno filters, so I can easily see what is the main plan and what is the reno filter (design) option, while I am working on the plan.
Of course the GO is turned off for final output.
