This is a last stand try, but I highly doubt it will work.  If the BC Liberals fall and the LG doesn't call another election, the party will dump Clark, so once a new leader is in place they can set their own policies.  Whether it will work or not is a different story, although there is a strong pro free enterprise vote in BC and the alliance will have many pitfalls so a new leader would help especially if they were not associated with the past government.  Peter Milhobar and Ellia Ross would be my top two choices as replacement leader.
