Quebec, with a PQ-QS merger

This is a bit of a fun map, rather than something based on hard math. In short, I've combined the projected PQ+QS vote per riding, and multiplied it by roughly 90% to produce a somewhat realistic "merged vote". I suspect that if the PQ wins under 10 seats that such a merger may indeed be realistic. Regardless, here is the map:

As you can see, the CAQ still has the edge here, but the merged PQS does very well.

This gives you some idea of what the vote patterns of a merged party might look like.
