No. Even if you could change to Sabon, you would not be happy with it. For one, it's not a monospaced typeface, so character columns would not align on the screen. This would be especially irksome in the DAT section of your programs. For another, it would not include glyphs for the Prop Tool's special graphics characters.
If you switch to BST you can use whatever font you want. For programming a monospaced font works wonders, specially of interest because Spin depends on indentation (like python)
