So your skirting is part of the wall composite and you are using a profile modifier to adjust the skirting thickness?
You might be able to use this as modifiers can be used in property expressions.
I will have to have a play with it over the weekend.
If your skirting was a separate object or beam then it would be easy, but of course it would not automatically cut for openings.
