I have a window that is to be removed (width marked by witness lines on the right) and replaced by a larger series of windows. In "Demolishing" this window, a "New" wall is created to fill the hole left behind. A new set of ganged windows is then created spanning over this hole.
It would appear that "New" walls created by "Demolishing" prevent windows, and I would assume doors, from ganging in plan within their area? Is there something I have missed or some work around to get them to gang properly?

As in create a second wall set to "New" in which the new windows live? I guess that would work.

Another option…
Working on the principal of modelling as it’s built, situations like yours had always been a bit of a headache e.g. splitting walls vertically & horizontally, demolishing walls that didn't need to be demolished etc. This all changed for me with the introduction of the opening tool & made renovation projects (the vast majority of work we do) so much easier.
Each door/window always has an equivalent opening (it carries the same ID as the door/window for ease of reference). If the door or window is removed, the opening remains…no automatic replacement of sections of wall…just like real life. Then the process for a new door/window would be as follows…
Direct replacement…just add to wall & sit over the opening
Smaller replacement…add new piece of wall to opening, then add new smaller window to new wall
Larger replacement…add new larger opening (I normally make this bigger than the new window/door to cover lintel installation & work to jambs) to existing wall & mark opening as proposed. Add new piece of wall to fill the new opening, then add door/window to new wall
The openings & new walls can all be scheduled & the section of wall affected by the new proposed opening, shows as demolished. Apart from seeing an axis line & cross at each opening (intentional but tailored for each view), the only imperfection is that you can’t limit the 2D graphical representation of the opening to a particular story i.e if it spans two stories, then it’s shown on both. Having said that, I quite like it now but it would help to tidy up views for the untrained eye…

But in the case of renovation filters, I find it is better to remove and replace (demolish and new) entire elements, and in the case of windows and doors the wall (or portion of the wall) that the door/window belongs to.
So you may be demolishing an existing window and replacing with a bigger or smaller one, then demolish a section of the wall at least as big as the largest of the windows you are swapping.
In reality you may not need to demolish the wall, but it works better in Archicad.
Same when you just need to add a new skin to a wall.
You don't need to physically demolish the wall, but in Archicad you do if you want to replace it with a single wall composite.

Before the opening tool, the way you suggest doing it, is the way I used to model (but replace composite with complex profile with profile modifiers). However, having now used the opening tool method on various renovation projects involving significant changes to the existing building structure, I find that it achieves the same results & more e.g. accurate assessment of demolition areas, fine tuning of opening sizes especially below doors where floors pass through etc
As for new skins, I always model finishes separately to the core wall structure, so I just add the new skin e.g. plasterboard & skim dabbed to walls, to the existing wall. The room already has a zone touching the existing wall internal boundaries, so just select a standard complex profile & magic wand (with offset) to zone boundary. Fine tune each skin using the profile modifiers, then add each wall passing over an opening, to the opening. This way, I can just schedule the new skin & highlight it as a new element using graphic overrides…

Then you could just associate the extra skins to the current door/window object.
Hopefully one day this can be a reality - I think once GS creates a polygonal opening option, then it could be possible.

With your method, how do you get it to show the demolished windows in plan? Their openings get overridden by the new Opening as empty fills when the Opening is set to
