Does "structural majority" mean absorption and integration into the People Power Party?

At this rate, it makes no sense for part of the People Power Party to be absorbed by the Democratic Party.
However, it seems possible for half of the Democratic Party to be absorbed into the People Power Party.
Does this mean 2/3 of Honam will be absorbed into TK?
Just like how 2/3 of PK was absorbed into TK during Kim Young-sam's three-party merger.
