Tire width isn't nearly as detrimental to speed as you seem to think.
A high quality slick tire can be fast rolling even if it's 35mm wide.
Conversely, a low quality 28mm tire can be heavy and slow even if it's thin.
You will always be slower if you ride upright because wind resistance is the biggest impediment to speed.
But yeah, just buy some quality fast rolling slick tires, even if they are 35mm or 38mm wide.
