That's silly.  Of course it's doable.  MIME allows nesting, so there's 
no reason to modify MIME parts.

I wrote a filter for the Courier mail server that does this, on a 
customer's behalf:

Not that I *like* adding signatures.  I think it's a bad practice that 
people abuse, mostly to add disclaimers or demands that have no legal 
backing.  I'm just saying that it's possible to do this and not break 
anything.
