Ability to edit basic Bootstrap / Bootswatch SCSS files

Are you planning to add editing options for basic Bootstrap or Bootswatch SCSS files using with project? I often get PSD projects (from graphic designers), which are completely different than Bootswatch templates. Currently, when I want to modify the original CSS classes, I have to use the overrides in the additional code. So it would be very useful to specify my own parameters, eg colors (primary, secondary), gutter-width, border-radius, paddings, margins, font sizes etc.
