Then what's the point? You wanna trick them and then at the interview say 'surprise, I got a degree!'? If they dont recognise pte degree, then why work there? You should head for private sector, gain exp, then come back with exp so they will consider it a mid-career switch. Instead, if you start at diploma position, it is not a confirmed thing that they will promote you JUST because you have a degree leh. If they really want to promote someone from the diploma pool to a degree position, they will pick the best and send him to take a degree. They wont pick you just because you have a degree already.
