The code's not *that* complicated, this time --- look in

Completion/Base/Core/_dispatch

The loop with _patcomps is handling the compdef -p.  Then the normal
name look-up happens.  This looks like it could be trashing your input.
With a judicious "if" around that bit, and probably also setting name
and comp in the loop above, you ought to be able to get it to work, I
think.
