I reported the inability to control the override line weight a few weeks ago. Like you, I want existing thinner and demo thicker (and, later, new thicker). GS is studying the issue.
There are several issues / problems. Graphisoft's approach has been to let us override the pen color only, not the weight, picking up the weight from the original content. But, it turns out, there are issues with fill overrides and composites and CP walls where it does not pick up the weight from ANY of the original skins, so there is no way to get a heavier weight using a different pen table.
Some of the pen override issues are bugs IMHO, and others are just choices that GS made in how this would be implemented that perhaps some of us disagree with.
If your walls are simple (not composite or CP) walls, then by assigning different pens to the original walls, you can create a pen table that changes the weights of those pens for the demo plan to get the look that you want. Personally, I would much rather have the override pen weight (rather than just color) apply to get the desired appearance more simply.
This extra step of pen assignments has to be a mistake, bug or at least an oversight IMHO. It makes no sense to be able to quickly mark a door as 'demo' - for automatic generation of plans - only to have to tediously also change all of the pen assignments for that door in order for it to appear with a heavy line in the demo plan. Etc. Defeats the purpose of overrides. (I didn't test with doors/etc - maybe that part works. Only tried walls and gave up.)
Another thing that might work is the tried and true method of stacking multiple drawings on top of each other on a layout... create a view that shows existing less demo, show that drawing with a thin and/or gray pen set, create another view that shows only demo bits - and show that drawing with the thicker pen set and stack it on top of the first.
