there is no easy way to do what you want, different bed widths, different bedside cabinets all contribute to different results.
honestly i can see this ending in disappointment, better to have a single window that annoys the wife now but she wont notice it in 2 seeks after moving in, the bedside cabinets/ bed will likely annoy you for a lot longer
moving the windows after consent would likely need to have it gone over again by the council.
