I can give that a qualified yes. Using the Custom Command option of content, I was able to create a content file that initiates the _WallAdd command, then specifies a particular wall style. Unfortunately, if that style does not already exist in the target file, the wall style will not be imported [even if it exists in the content file].
The workaround is to include a block that contains a wall of that style as part of the content. You would still have a useless block to purge out if that does work, but at least you would not have to erase it first, and it does start the command for you, so you get right to drawing.
I used the WALL layer key for this content, but if you had another layer key you wanted to use, you could specify that instead. It will only affect the parent layer, mostly Shrinkwrap with the out-of-the-box styles, not the subcomponents, but it might be useful for existing or demolition wall styles that already have their components mapped to existing or demolition wall layers.
I will post my experimental content file to the ADT Content newsgroup if you want to take a look at what I did.
