All I can think of is "shan't", the contraction of "shall not". It's particularly unappealing as "shan't" is often used in books as the favourite word of rude and stubborn young children (it's used that way in the
Harry Potter books but it's also not uncommon in Victorian-era fiction).
So an absolute 'no' from me, sorry.
