Terry Milewski digs up an essay penned by Stephen Harper and Tom Flanagan around the same time the former was saying things like this. It sketches a potential Reform-Progressive Conservative “alliance”—as opposed to a merger—and then turns to the question of Quebec.

If Quebec stays in Confederation, the Bloc will either disintegrate or become an autonomist party, participating in federal politics as a representative of Quebec’s specific interests. Philosophically, it is logical for liberals to offer Quebec money and privileged treatment, while conservatives find it easier to offer autonomy and enhanced jurisdiction. On that basis, a strategic alliance of Quebec nationalists with conservatives outside Quebec might become possible, and it might be enough to sustain a government. None of this will be easy or even likely. But experience shows that a monolithic conservative party is unworkable; so conservatives who are unhappy with a one-party-plus system featuring the Liberals as the perpetual governing party may have little choice but to construct an alliance, at least of the two anglophone sisters, and perhaps ultimately including a third sister. An alliance would face many difficulties, to be sure, but it would also have two great advantages. It would reflect the regional and cultural character of Canadian society, and it would give that character an institutional expression. Also, it would allow leaders of the regional parties to defend necessary compromises as precisely that — necessary compromises. In a single national party, compromises have to be defended as party policy, which tends to drive dissenters out of the fold.

Mr. Harper and Mr. Flanagan then concluded with an ode to political cooperation, including mention of the “coalition governments” that exist in Europe.
