An interesting thing is that during the negotiations following the 2010 election, Gordon Brown offered the Lib Dems AV *without a referendum*. Now, its highly unlikely that he could have got that past the PLP, but what if, Cameron made the same deal to get the Lib Dems onside? Now, you might well argue that Cameron also wouldnt have been able to get his backbenchers to go for it, but I think the Tories would be somewhat hungrier for power at this time, and by combining it with the redrawn boundaries it could have passed.
An alterantive (thoguh perhaps requiring much more speculation) is what if the Lib Dems had asked for STV in local authority elections? This may well have preserved their base of councillors, which in OTL has been seriously eroded, thus affecting their ability to campaign.
