You can say no way, but VFR into IMC is one of the main causes of GA accidents, so creating more buffer should alleviate this. The second reason is that someone on a basic drivers licence has not been scrutinized for how they will handle IMC flight operation so it is possible they could be more susceptible to disorientation in cloud due to various medical reasons, but would have no issues with strong visual cues in VMC. Hence why I think adding wider margins for VMC for the restricted medical has merits, yet restrictions on certified seats on a type has none. I can't think of many places in Australia where a 2000ft ceiling would be hard to achieve on most days. We are talking about a restricted PPL here so you could easily fix this by getting a full medical and IFR rating. It's comments that indicate you would use your increased freedoms to do more scud running in marginal conditions that worries regulators about these types of changes. This is about having hasell free recreational flying, not some circumvent to conduct everyday business or getting places on every occasion.
