Are you sure this is possible, considering the signature is stored in the 
header?

If I read this strace dump of the server, it wouldn't be possible:
writev(8, 
[{"l\1\0\0012\0\0\0\24\0\0\0\217\0\0\0\1\1o\0\21\0\0\0/org/kde/selftest\0\0\0\0\0\0\0\6\1s\0\20\0\0\0org.kde.selftest\0\0\0\0\0\0\0\0\2\1s\0\20\0\0\0org.kde.selftest\0\0\0\0\0\0\0\0\3\1s\0\4\0\0\0ping\0\0\0\0\10\1g\0\4aaay\0\0\0\0\0\0\0\7\1s\0\6\0\0\0:1.161\0\0", 
160}, {".

50}], 2) = 210

Note the "aaay" part in the first vector of the syscall.

Not to mention getting the alignment right.
