Avast has spent a lot of time giving the whole avast brand the same look, website, forum, blog, etc. and the avast user interface the same corporate look. So I too rather doubt that will change.
As far as being able to move buttons around, etc. I think that is a poor idea, you only have to view the forums to see that we constantly use images to a) answer questions without the need of very long text only answer and b) we often ask users to post images of their settings, etc. in relation to problems.
So there needs to be a degree of consistency in the interface, this is more important when you also have different language versions involved, whilst the text, titles, button names might be different, the locations are consistent and help in following any explanation.
