I find that highly unlikely since I'm guessing their supporters, while maybe not so zealous about separatism anymore, still vote Bloc because they represent Quebec and only the interests of Quebec. Merging the Bloc with another federal party would dilute that voter base and could even cause a more extremist pro-Quebec pro-sovereignty party to fill the gap.
The Bloc have shown in the past that they are capable of working with any party in the House so long as Quebec will benefit. Even though "Liberal" may be just as dirty a word in Quebec as it is in Alberta, both legacies of Trudeau-era policies, the Bloc seems more apt to work with the federal Liberals than with the conservatives, especially since urban Anglos in Quebec seem to vote Liberal not NDP or Conservative.
