You would have to prove to him, that you have fulfilled the all the requirements (including an ATO syllabus), which are stated in the Part 61 type rating requirements (READ it !!! on CAA website) and what experience you already have (FAA etc). Then you do the skills test flying in the right hand seat with a DE. If he signs you out - then yes you will be issued with a 1P.
But as I have said before - the testing standards officers at the SACAA are the only ones that will give you an answer to your specific case - in fact it does not even matter, what anybody else says here in the forum - they do provide individual solutions in accordance with the part 61 Law in order to satisfy themselves. Worst case would be that they just won't accept it from the start.
