Sorry to bump this thread, but it looks like there's a movement to form a majority coalition in the Alaska Senate as well:

If the House majority coalition keeps control of the House and this majority coalition assumes power in the Senate, this would be the first time since the 1993-1994 session that both houses of the legislature were controlled by coalitions (at least according to Wikipedia).
The State Senate ended up staying under Republican control as opposed to the bipartisan coalition, but today Rep. Louise Stutes was elected as the permanent House Majority leader for this session:

Although a majority caucus hasn't been formed yet, I think that this move makes it a near certainty that the coalition government is here to stay at least until 2023.
