Congrats on your room, nothing like a dedicated room for 2 or multi channel! You mention your ceiling, what is it? Finished? Flat or are joists exposed? I find the floor and particularly the ceiling are the biggest problem with reflective sound.
And what are you missing in the sound stage? Specificity of imaging? or instrument separation? holography? Generally the more space between your speakers the more of these characteristics are enhanced. Closer the speakers the narrower the stage but it can give a more rich presentation and stronger image.
Yogi is right about speaker placement - if you have not spent many hours moving them around you will never find the sweetest spot. Sounds like you have plenty of room to experiment. Personally, I am more about the tone and balance than soundstaging qualities.
Good luck - now get to work moving those B&W's around!
