No amount of sticking plaster will save the Lib Dems as a party with integrity. They have sold their birthright to the Tories who are gleeful at their ongoing demise. They will be decimated in the local elections in May and indeed if anyone is actually examining the odd by-election result at county or local council level (e.g. Dover) they are hardly registering a vote.
Those Lib Dem ministers who know the deal is over should step aside and rejoin their own party before it becomes an irrelevance and is swept aside by the Tory changes to English constituencies.
Clegg meanwhile will announce he is taking the remnants of the Orange Party into the Tory Party permanently.
"Sold" and "river" come to mind.
