Nope.  For example, the code that systemtap functions are translated to
have a rather different API/ABI at the C level, e.g., involving putting
parameters into an explicit stack structure (context*).  You can
probably hack together something that would work for your script, based
on an examination of stap -p3 output, but is not a well-supported
technique.
