Now that you ask, let me deal with this in terms of key qualifications (which is where it all should start, not by naming names first up):
1. First up, I would keep zero persons from the current ARU board. The alignment of this current ARU board with the strategic and operational needs of the code today is like that of choosing a hippopotamus upon which to play polo.
2. I would design a 7 person board - larger boards notoriously decline in coherence and effectiveness.
3. I would source a Chairperson with a successful history in the building and strategic leadership of an international pro sporting code based upon important amateur feeder roots. Certainly does not have to be rugby. And ideally with much international experience relating thereto.
4. I would require a Rugby Coaching Stream Representative. A person with long experience of either being a successful elite rugby coach and/or building a successful bottom-to-top rugby coaching infrastructure (btw and e.g., Ewen McKenzie comes to mind for this role). Not at all necessarily from Australia, btw.
5. Next a 'Grass Roots Representative'. 1 representative elected by a formal ballot process every say 3 years by members of, or directly nominated by, all the grass roots amateur rugby clubs in Australia.
6. The CEO - critically, like the Chair, with similar qualifications. Certainly not an 'insider elite rugby mate'.
7. I would allow RUPA to nominate 1 person as the Rugby Players' Representative but this person must be duly elected by all pro Australia-based rugby players as per 5 every 3 years and certainly not a RUPA 'insider mate'.
8. Next, 1 person os suitable experience nominated by the 5 largest (by $s spent) funding sponsors of any layer of Australian rugby over the past 3 years and rotating every 3 years.
9. Finally, to make 7: 1 person chosen by a Nominations Committee as having notable managerial qualifications and strategic business expertise in a field reasonably designated as having relevance to a professional sporting organisation like rugby, e.g., a highly people-intensive business, perhaps media, and such like.
