Mr Turnbull supported by Ms Bishop or Mr Robb. Though few could manage to replicate Mr Howard's 'everyday' style, I think that Mr Turnbull has what it takes be a capable Opposition leader (and a successful PM, one day). Given the nature of today's Labor (i.e., as aspirational as the Libs), it's unlikely that Mr Turnbull's personal wealth would be a political liability, and his string of successful careers outside of politics would limit the impact of any argument that questions his experience.
As for the position of deputy, both Ms Bishop and Mr Robb seemingly posses not only the traits required of a potential leader (skill, ambition, ticker, etc.), but also the political capital that the Liberal party as a whole needs if it is to reestablish itself (Ms Bishop through the strength of the Party in WA and through her WA foundraising connections, and Mr Robb through his previous roles with both the National Farmers Federation and the Liberal Party). That said, both would represent something different. Whereas Julie Bishop would in theory reinforce Mr Turnbull's moderate liberal outlook (see
here), Mr Robb, as a self proclaimed conservative (e.g., he was the Convenor of Conservatives for an Australian Head of State and see
here), would balance the leadership ticket and preserve the oft-mentioned broad church tradition of the Liberal Party.
As always, time will tell, but from outside the castle walls looking in, I think that a Turnbull and Bishop/Robb ticket would work well for both the Liberals and the country at large. As for the other contenders for the leadership positions, Mr Nelson seems capable, but his past and his at times reactionary style may not play well with many, and Abbott is now out of the race (see
here). For the position of deputy, from what I can gather Mr Pyne seems OK but when considered alongside Ms Bishop and Mr Robb he just wouldn't cut the mustard.
I sound like such a wanker, trying to pass myself off as being somewhat informed. Go me!
Edit: A simple leadership change will not address all of the other problems facing the Liberal Party, but it is a start.
